摘要

In order to improve the stability of channel equalization and communication transmission of the wireless communication system, wireless communication system needs to design the controller, the controller design scheme of wireless communication based on DSP technology, the high speed signal processing chip ADSP21160 processor as the main control chip, the overall design of a wireless communication controller, including communication module AD module signal the hardware of the system, signal amplifier, detector module, amplifier module, modulation module, main control module and output module. The input signal in wireless communication amplifying and filtering processing, channel optimization control using DSP communication signal modulation and demodulation, controlled by the internal clock oscillator signal for wireless communication, wireless communication channel optimization of control system. The test results show that using the method of wireless communication control system, the system has better channel equalization, lower output error code and higher control quality.%为了提高无线通信系统的信道均衡性和通信传输的稳定性,需要进行无线通信系统控制器设计,提出基于DSP技术的无线通信控制器设计方案,采用高速信号处理芯片ADSP21160处理器系统作为主控芯片,进行无线通信控制器的总体设计,系统的硬件组成模块包括通信信号AD模块、信号放大器、检波模块、增益放大模块、调制解调模块、主控模块和输出接口模块.对输入无线通信信号进行放大滤波处理,采用DSP进行通信信号的信道优选控制,采用内部时钟振荡器进行无线通信信号的调制解调控制,实现无线通信信道优选控制.系统测试结果表明,采用该方法进行无线通信控制,通信系统的信道均衡性较好,输出误码较低,控制品质较高.
