[0033] In the related art, a communication apparatus generally uses a 5G baseband chip or other mobile phone chip. However, due to the large variety of antennas, the mobile phone chip has poor processing performance for some functions or lacks some processing functions, and thus needs to be externally connected to a processor module for processing. In other words, the antenna processor needs to be additionally connected to multiple external processor modules to realize the functions of multiple antennas. Therefore, the present application provides a communication apparatus 10.

In this way, the integration of the communication device 10 can be improved, the cost of the communication device 10 can be reduced, and the signal quality can be improved.
[0038] Specifically, the integration of multiple external processor modules in the present application is used to complete the reception and transmission of wireless signals by the radio frequency transceiver module 121, and the antenna processor 122 can communicate with the radio frequency transceiver module 121 for signal processing. When receiving wireless signals, multiple antennas can receive wireless signal data and transmit it to the radio frequency transceiver module 121, which processes the data and transmits the processed data to the antenna processor 122 for data processing. Then the antenna processor 122 can transmit the processed data to other electronic devices; when transmitting wireless signals, the data of other electronic devices is transmitted to the antenna processor 122, which processes the data and transmits the processed data to the radio frequency transceiver module 121, which transmits the data through wireless signals through multiple antennas.

[0044] Specifically, the radio frequency transceiver module 121 has a high-precision positioning antenna interface, wherein the high-precision positioning antenna interface includes a single antenna interface and a double antenna interface. The single antenna interface can be connected to a single antenna through a coaxial cable, and the double antenna interface can be connected to a double antenna through a coaxial cable. The single antenna and the double antenna need to be placed separately and spaced apart by more than 0.8 meters from each other to avoid signal interference and errors between the single antenna and the double antenna. The radio frequency transceiver module 121 also has an FM antenna interface and an AM antenna interface, which can be connected to an FM antenna and an AM antenna through a coaxial cable. The FM antenna and the AM antenna are used to receive wireless broadcast signals, which facilitates the playing of radio programs on the media system on the vehicle after the wireless broadcast signals are processed by the communication device 10.
[0045] In addition, the radio frequency transceiver module 121 also has a DAB antenna interface, which can be connected to a DAB antenna through a coaxial cable. The DAB antenna is used to receive digital audio broadcast signals, which facilitates the playing of digital audio broadcast on the vehicle audio system after the digital audio broadcast signals are processed by the communication device 10. The radio frequency transceiver module 121 also has a GPS antenna interface, which can be connected to a GPS antenna through a coaxial cable.

The WIFI & BT antenna interface can be connected to a WIFI & BT antenna through a coaxial cable, thereby realizing the connection between the vehicle and the wireless local area network, and realizing the wireless connection between the vehicle and the Bluetooth.
[0047] It should be noted that FM refers to frequency modulation (i.e., Frequency Modulation); AM refers to amplitude modulation (i.e., Amplitude Modulation); DAB refers to digital audio broadcasting (i.e., Digital Audio Broadcasting); GPS refers to global positioning system (i.e., Global Positioning System); V2X refers to vehicle-to-external information exchange (i.e., Vehicle to Everything); 5G refers to the fifth generation communication technology; 4G refers to the fourth generation communication technology; WIFI refers to wireless local area network; and BT refers to Bluetooth, a short-range wireless communication technology.
[0048] Referring to FIG. 2, in some embodiments of the present application, the communication device 10 can also include a circuit board 12 and a housing 11. The radio frequency transceiver module 121 and the antenna processor 122 are arranged on the circuit board 12, and various antennas are arranged on the circuit board 12 or the housing 11. In this way, the integration of the communication device 10 can be improved, the cost of the communication device 10 can be reduced, and the signal quality can be improved.
[0049] Specifically, the radio frequency transceiver module 121 and the antenna processor 122 can be integrated on the circuit board 12 to reduce the length of the wire arrangement between the radio frequency transceiver module 121 and the antenna processor 122 and improve the transmission efficiency; the high-precision positioning antenna, the frequency modulation FM antenna, the amplitude modulation AM antenna, the digital audio broadcasting DAB antenna, the global positioning GPS antenna, the vehicle-to-everything V2X antenna, the 5G antenna, the 4G antenna, the wireless network WIFI antenna, and the Bluetooth BT antenna can be made into on-board antennas, that is, multiple antennas can be directly arranged on the circuit board 12 to improve the integration of the communication device 10, and compared with the related art in which the antennas are arranged outside the communication device 10, the shell 11 of the processor module is reduced, the cost is reduced, and in addition, by integrating the antennas on the circuit board 12, the number of coaxial cables between the antennas and the antenna processor 122 can be reduced, and the length of the coaxial cables can be reduced, thereby improving the quality of the signal.
[0050] In addition, multiple antennas can be arranged in the shell 11, which can improve the integration of the communication device 10 and reduce the distance between the multiple antennas and the radio frequency transceiver module 121, thereby reducing the number of coaxial cables and the length of the coaxial cables, and further improving the quality of the signal.
[0051] Referring to FIG. 1, in some embodiments of the present application, the multiple antenna interfaces further include at least one reserved antenna interface; specifically, since the multiple antennas are received or transmitted through the radio frequency transceiver module 121 to the antenna processor 122, the radio frequency transceiver module 121 can have at least one reserved antenna interface, which facilitates adding new functions to the communication device 10 and improves the applicability of the communication device 10.
[0052] Referring to FIG. 1, in some embodiments of the present application, the radio frequency transceiver module 121 has at least one communication interface connected to the antenna processor 122, and the communication interface is a serial interface or a parallel interface; optionally, the radio frequency transceiver module 121 has a serial interface, and the antenna processor 122 is connected to the radio frequency transceiver module 121 through the serial interface, so that the radio frequency transceiver module 121 and the antenna processor 122 can be connected through fewer wires, which simplifies the layout of the communication device 10, reduces the cost of the wires, and reduces the signal interference between the wires. Optionally, the radio frequency transceiver module 121 has a parallel interface, and the antenna processor 122 is connected to the radio frequency transceiver module 121 through the serial interface, so that multiple data bits can be transmitted at the same time, providing higher data transmission efficiency and thereby improving the working efficiency of the communication device 10.
[0053] Referring to FIG. 1, in some embodiments of the present application, the antenna processor 122 has at least one memory interface for connecting an external memory 13; in this way, the antenna processor 122 has sufficient bandwidth to cache or store, improving the working efficiency of the communication device 10. For example, the memory interface can be an MCP interface for connecting an external MCP memory (i.e., Multiple Chip Package).
[0054] In some embodiments of the present application, the antenna processor 122 is configured to meet the V2X signal processing capability; specifically, in combination with the foregoing embodiments, the plurality of antennas can include a vehicle-to-everything V2X antenna, the plurality of antenna interfaces can include a vehicle-to-everything V2X antenna interface, the vehicle-to-everything V2X antenna is connected to the vehicle-to-everything V2X antenna interface of the radio frequency transceiver module 121 through a coaxial cable; when the communication device 10 is working, the radio frequency transceiver module 121 can receive and send wireless signals through the vehicle-to-everything V2X antenna, and the radio frequency transceiver module 121 communicates with the wireless processor, the wireless processor is configured to meet the V2X signal processing capability, and can process the data sent by the radio frequency transceiver module 121 to the wireless processor; compared with the insufficient computing power of the processor in the related art, which needs to additionally arrange a V2X computing power expansion module, the embodiments of the present application can improve the integration of the communication device 10, reduce the arrangement length of the wire harness in the communication device 10, and improve the signal quality.
[0055] Referring to FIG. 1, in some embodiments of the present application, the antenna processor 122 can have an optoelectronic conversion interface, and the antenna processor 122 is configured to communicate with the external device 20 through the optoelectronic conversion interface; in this way, the transmission efficiency between the antenna processor 122 and the external device 20 can be improved, and the arrangement length of the wire harness can be reduced.
[0056] In the related art, the antenna processor 122 has a USB interface, a CAN interface, etc., and the antenna processor 122 can perform data transmission between the antenna processor 122 and the external device 20 through these interfaces; however, although the USB interface has a relatively high transmission rate, it does not meet the long-distance and unlimited needs of vehicles, and the transmission rate of the CAN interface is relatively low, which does not meet the large data transmission of the communication device 10; therefore, in the embodiments of the present application, the antenna processor 122 can have an optoelectronic conversion interface, wherein the optoelectronic conversion interface can be an optical fiber transceiver or an optoelectronic conversion module; in other words, the optoelectronic conversion interface of the antenna processor 122 can be connected to the external device 20 through an optical fiber; in this way, the data transmission efficiency and the data transmission amount between the antenna processor 122 and the external device 20 can be improved. In combination with the foregoing, when the USB interface is used, the antenna processor 122 needs to be arranged close to the external device 20; however, in the embodiments of the present application, the antenna processor 122 is connected to the external device 20 through the optoelectronic conversion interface, which can eliminate the need to arrange the antenna processor 122 close to the antenna, and improve the arrangement flexibility of the communication device 10.
[0057] Referring to FIG. 1, in some embodiments of the present application, the antenna processor 122 is integrated with an inertial measurement unit (i.e., IMU in the figure), and the antenna processor 122 is configured to receive and process data collected by the inertial measurement unit; in this way, the measurement of three-axis attitude angle (or angular rate) and acceleration can be realized by the antenna processor 122, without the need to add an inertial measurement unit outside the antenna processor 122, thereby improving the integration of the communication device 10 and reducing the volume of the communication device 10.
[0058] In detail, in the related art, since the communication device 10 adopts a 5G baseband chip or other mobile phone type chip, it cannot realize the function of the inertial measurement unit, therefore, in the embodiments of the present application, the inertial measurement unit can be integrated in the antenna processor 122, so that the antenna processor 122 can realize the function of the inertial measurement unit, i.e., measure the three-axis attitude angle (or angular rate) and acceleration of the vehicle, thereby improving the integration of the communication device 10 and further reducing the volume of the communication device 10.
[0059] Referring to FIG. 1, in some embodiments of the present application, the antenna processor 122 is integrated with a power management unit (i.e., PMIC in the figure), and the power management unit is configured to supply power to the antenna processor 122; in detail, the power management unit can be responsible for managing and distributing power to various parts in the antenna processor 122 to assist the antenna processor 122 to better realize data processing; in this way, the integration of the communication device 10 can be improved and the volume of the communication device 10 can be reduced.
[0060] Referring to FIG. 1, in some embodiments of the present application, the antenna processor 122 has at least one of a GPIO interface, an I2C interface, an SPI interface, and a USB interface, which are used to externally connect devices for communication with the power management unit of the radio frequency transceiver module 121 and / or the antenna processor 122; alternatively, the antenna processor 122 has a GPIO interface, an I2C interface, an SPI interface, and a USB interface, through which a technician can communicate with the antenna processor 122 and the power management unit of the radio frequency transceiver module 121 and / or the antenna processor 122, facilitating the technician to perform fault detection, remote control, monitoring, data exchange, diagnosis and update, etc. operations on the power management unit of the radio frequency transceiver module 121 and / or the antenna processor 122, thereby improving the working stability of the communication device 10.
[0061] It should be explained that GPIO stands for General Purpose Input / Output, which is an electronic interface that allows microcontrollers or computers to input and output digital signals with external devices, and the GPIO interface is usually used to control and monitor various sensors, switches, LEDs, etc.
[0062] I2C stands for Inter-Integrated Circuit, which is a multi-master, serial computer bus that allows multiple "slave" devices to communicate with a "master" device. I2C interfaces are commonly used for low-speed peripherals such as temperature sensors, real-time clocks, and more.
[0063] SPI stands for Serial Peripheral Interface, which is a high-speed, full-duplex, synchronous serial I / O interface commonly used to connect central processing units (CPUs) with various peripherals such as SD cards, digital signal processors (DSPs), and more.
[0064] USB stands for Universal Serial Bus, which is a widely used interface technology for connecting computers with external devices. USB interfaces support plug-and-play and hot-swapping, enabling the transmission of data and power. There are various standards for USB interfaces, such as USB 1.1, USB 2.0, USB 3.0, and more, each with different data transfer rates.
[0065] Referring to FIG. 1, in some embodiments of the present application, the antenna processor 122 also has a UART interface for debugging and printing data of the antenna processor 122. Specifically, the UART interface can be used for debugging the antenna processor 122, where a technician can monitor the behavior of the antenna processor 122, read error logs, or update algorithms within the antenna processor 122 through the UART interface when the antenna processor 122 is in the development and debugging stage. Of course, data in the antenna processor 122 can also be printed through the UART interface to facilitate analysis of the antenna processor 122.
[0066] It should be noted that UART is the abbreviation of Universal Asynchronous Receiver / Transmitter, which is a full-duplex, asynchronous communication interface that works at the data link layer and supports RS232, RS485, and other specification circuits.
[0067] Referring to FIGS. 1-3, according to the communication device 100 in the embodiments of the present application, the communication device 100 includes the communication apparatus 10 and the central computing processing unit in the above-mentioned embodiments, and the central computing processing unit communicates with the antenna processor 122. By applying the aforementioned communication apparatus 10, the cost of the communication device 100 can be reduced, and the signal quality can be improved.
[0068] Specifically, the antenna processor 122 can integrate multiple external processor modules and communicate with the radio frequency transceiver module 121 to use the radio frequency transceiver module 121 to receive and transmit wireless signals; when receiving wireless signals, multiple antennas are connected to the radio frequency transceiver module 121 through multiple antenna interfaces for transmitting unlimited signal data to the radio frequency transceiver module 121, and the radio frequency transceiver module 121 processes the data and transmits the data to the antenna processor 122, and the antenna processor 122 processes the received multiple data and sends them to the external device 20; when transmitting wireless signals, the external device can transmit data to the antenna processor 122, which is processed by the antenna processor 122 and then sent to the radio frequency transceiver module 121, which can transmit data through multiple antennas by wireless signal. Compared with the related art, in which multiple additional processor modules are connected to the antenna processor 122, the application can reduce the cost of the communication device 100.
[0069] The radio frequency transceiver module 121 has multiple antenna interfaces, which can include high-precision positioning antenna interfaces, FM&AM antenna interfaces, DAB antenna interfaces, GPS antenna interfaces, V2X antenna interfaces, 5G antenna interfaces, 4G antenna interfaces, and WIFI&BT antenna interfaces. These interfaces can be used to connect to multiple antennas to facilitate the radio frequency transceiver module 121 to receive multiple wireless signals and transmit data to the antenna processor 122 for processing; for example, the FM&AM antenna interface can be connected to the FM&AM antenna, so that the radio frequency transceiver module 121 can transmit the received wireless broadcast signal to the antenna processor 122 for data processing, and then the antenna processor 122 can transmit the processed data to the sound equipment inside the vehicle for playing; for example, the 5G antenna interface can be connected to the 5G antenna, so that the radio frequency transceiver module 121 can transmit the received 5G signal to the antenna processor 122 for data processing, and then the antenna processor 122 can transmit the processed data to the equipment inside the vehicle to facilitate the equipment inside the vehicle to communicate through 5G.
[0070] Further, the communication device 10 further comprises a circuit board 12 and a shell 11, the radio frequency transceiver module 121 and the antenna processor 122 can be integrated on the circuit board 12, so as to reduce the length of the wire harness arrangement between the radio frequency transceiver module 121 and the antenna processor 122, and improve the transmission efficiency; and the aforementioned high-precision positioning antenna, FM&AM antenna, DAB antenna, GPS antenna, V2X antenna, 5G antenna, 4G antenna and WIFI&BT antenna can be manufactured as on-board antennas, that is, a plurality of antennas are integrated on the circuit board 12, so as to reduce the length of the coaxial wire harness between the radio frequency transceiver module 121 and the plurality of antennas, improve the signal quality of the communication device 10, and the integration. Of course, a plurality of antennas can be arranged on the shell 11, which can also improve the integration of the communication device 10, reduce the distance between the plurality of antennas and the radio frequency transceiver module 121, thereby reducing the number of coaxial cables and the arrangement length of the coaxial cables, and further improving the signal quality.
[0071] In addition, the radio frequency transceiver module 121 also reserves at least one antenna interface, which facilitates the connection of the radio frequency transceiver module 121 to a new antenna, and adds new functions to the communication device 10. The antenna processor 122 has at least one memory interface for connecting an external memory 13, so as to provide sufficient bandwidth for the antenna processor 122 to cache or store, and improve the working efficiency of the communication device 10.
[0072] In addition, the antenna processor 122 can have the capability to meet the V2X signal processing, so that an additional V2X expansion computing module is added to the antenna processor 122, which improves the integration of the communication device 10 and reduces the size of the communication device 10. In addition, the antenna processor 122 is integrated with an inertial measurement unit, in other words, the three-axis attitude angle (or angular rate) and acceleration of the vehicle can be measured through the antenna processor 122. In addition, the antenna processor 122 is also integrated with a power management unit, which supplies power to the antenna processor 122 through the power management unit, thereby improving the integration of the antenna processor 122.
