Problems solved by technology
Most of the applications are based on field programmable logic gate array (FPGA) platform and digital signal processing (DSP) platform, and FPGA platform and DSP platform use digital signal as the medium of modulation and demodulation, but the existing application mode has The following disadvantages: 1. The carrier frequency is low, only tens of megahertz, which is not suitable for the high-speed requirements of modern mobile communications; 2. The working frequency band is narrow, and generally can only work within the frequency band of tens of megahertz; 3. The platform volume Larger, higher power consumption, not suitable as a carrier for portable mobile communications; Fourth, the signal transmission delay is large, and the signal distortion caused by parasitic parameters is relatively serious, requiring complex receiving system design to demodulate useful signals; Fifth, single Board cost is high

Embodiment 1
[0052] This embodiment provides an integrated transceiver. Specifically, this embodiment proposes an EBPSK integrated transceiver based on a complementary metal oxide semiconductor (CMOS) process. The integrated transceiver is designed based on a chip, that is, a receiver It is integrated with the transmitter on the same chip, and the transceiver uses the analog signal as the processing signal of the whole system, and the radio frequency circuit as the processing circuit of the whole system, so that it can avoid the digital signal as the processing signal in the prior art problems encountered. Further, the integrated transceiver described in this embodiment has fewer circuit modules, is simple and easy to implement, reduces design complexity, and saves cost. At the same time, since this embodiment uses a chip design, which greatly increases system integration and effectively reduces platform area, the integrated transceiver described in this embodiment can reduce system power ...

The embodiment of the invention discloses an all-in-one transceiver. The all-in-one transceiver comprises a transmitter and a receiver, wherein the transmitter is used for converting an acquired firstdigital signal into a first modulation signal, and modulating the first modulation signal, so as to convert the modulated first modulation signal into a first EBPSK (Extended Binary Phase Shift Keying) modulation signal and output the signal; the receiver is used for demodulating an acquired second EBPSK modulation signal to acquire a second modulation signal, and demodulating the second modulation signal, so as to convert the demodulated second modulation signal into a second digital signal and output the signal; the transmitter and the receiver are integrated in the same chip; and the firstmodulation signal modulated by the transmitter and the second modulation signal demodulated by the receiver are analog signals. The embodiment of the invention further discloses a terminal.
Description
technical field [0001] The invention relates to mobile communication technology, in particular to a transceiver and terminal. Background technique [0002] While the multimedia digital information source brings people pleasant audio-visual enjoyment and physical and mental satisfaction, it also puts forward higher and higher requirements for real-time transmission. With the continuous improvement of the transmission rate, the communication system is now becoming more and more high-frequency and broadband. However, wireless spectrum, like natural resources such as coal and oil, is a recognized precious resource. With the improvement of people's living standards and the increase in communication needs, the scarcity of spectrum resources has become more and more obvious, and it has become more and more a constraint for modern communication systems. unfavorable factors for development. [0003] In order to solve this contradiction, in recent years, more and more scientists and...
