A relay cooperative communication system based on nRF24L01 radio frequency(RF)module was designed. The system performance of relay cooperative transmission in comparison with the direct passing link is studied. The hardware system is composed of RF module and STC89C51 to realize data transceiving and transmitting. The implementation keys of system cir-cuit design and software design are described. The goal is to reduce the system error rate,and decrease the noise interference and the signal attenuation degree in channel. The test experiment results show that the relay cooperative communication imple-mented by this system has strong anti-jamming performance,and has improved the integration quality of the communication.
