摘要
为了解决扩频通信体制的通信速率相对较低而无法满足高速高清图像的无线传输通信需要的问题,文中对实现高速基带解调的一项关键技术,也就是载波相位跟踪技术进行了研究。
In order to solve the communication speed of the spread spectrum communication system is relatively low and unable to meet the communication needs of high-speed wireless transmission of high-definition image, a key technology is studied to achieve high- speed baseband demodulation, which is the carrier phase tracking technology.
