红外无线局域网PPM接收机的DSP实现

DSP Implementation of PPM Receiver in Wireless Infrared Local Network

光脉冲位置调制(PPM)通信具有光发射平均功率低峰值功率高的优点,在室内红外无线局域网得到应用。文中介绍一种建立在DSP器件(TMS320C30)上的PPM全数字接收机的结构和工作原理。

The optical pulse -position modulation (PPM) communication offers the advantage of high peak - power and low average - power, it is used in indoor wireless infrared local network. The paper describes the structure of all digital receiver based on DSP device. The various digital signal processing functions are discussed.
