摘要
设计一种基于n RF24L01无线射频模块的中继协作通信系统,研究中继协作传输相比于直传链路的系统性能。利用无线射频模块和STC89C51组成硬件系统实现数据收发和转发,阐述系统电路设计和软件设计的实施关键。以降低系统误码率为目标,最大限度减少信道中噪声干扰和信号衰减程度。测试实验结果表明,使用该系统实现的中继协作通信具备更强的抗干扰性能,提升了通信的整体质量。
A relay cooperative communication system based on n RF24L01 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 circuit 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 implemented by this system has strong anti-jamming performance,and has improved the integration quality of the communication.
