The embodiment of the invention provides a CPCI bus control type radio-frequency transmission board card and a CPCI bus control type radio-frequency transmitting-receiving board card. The radio-frequency transmission board card comprises a transmission channel which is used for carrying out the filtering, amplification, power control and frequency mixing of a 70MHz or 220MHz intermediate frequency signal from a baseband board card so as to convert the intermediate frequency signal into a 2MHz-3000MHz radio frequency output signal. The radio-frequency transmission board card also comprises a first frequency synthesizing system, and the system is used for executing quick frequency hopping, and generating dot frequency local oscillation needed by the transmission channel. The radio-frequency transmission board card also comprises a control system which is used for processing a CPCI interface protocol command, and configuring the first frequency synthesizing system. The radio-frequency transmission board card also comprises a CPCI interface, and the CPCI interface is used for the communication between the control system and the upper computer and supplying power to the radio-frequency transmission board card. The center frequency, receiving bandwidth and transmission power of the board card can be configured through a CPCI bus.
Description
technical field [0001] The example of the present invention relates to software radio communication technology, and more specifically relates to a CPCI bus control type radio frequency transmitting board and a transceiver board with parameters configurable. Background technique [0002] In recent years, with the rapid development of the radio system, the traditional hardware-based wireless communication system design method gradually cannot meet the multi-mode communication requirements, and the idea of software radio emerged as the times require. [0003] Software defined radio (Software Defined Radio, SDR) technology is a wireless communication system architecture proposed in recent years. It was first developed from military communication technology. Its basic idea is to configure hardware through software to achieve flexible reconfigurable features. Software The ultimate goal of radio is to free the communication system from the shackles of the hardware system structur...
