The electromagnetic compatibility of the printed circuit board, radio frequency circuit layout, microstrip transmission line, RF front-end circuit is also designed and analysed in the hardware design section. On the software work, the SPI driver and application programs of CYRF6936, serial communication protocols and wireless communication protocol programs are completed in the ICCAVR.In addition, the system management and analysis software is developed in the VC++6.0.At last, the feasibility of the spread spectrum wireless communication based train-ground communication system solution is verified by the system tests.The implementation of the radio station and the problems which solved through the design and test process have an important reference value on the application of spread spectrum communication technology in urban rail transit.
