A Synchronizing System in 4-time 4-frequency Coded Diversity Receiver

四时四频编码分集接收的同步系统

The D 4 R diversity receiver provides outputs in the same configurations.

接收器的D4R多样性提供的产出在同一配置.

The novel cooperative communication scenario takes both the direct link and relay link of secondary user into consideration for data transmission. Then the receiver of secondary user merges the signals from the two links to obtain diversity gain and improve system performance.

新的协作通信场景是指同时利用次级用户的直接链路和中继链路来协同传输数据，次级用户的接收端通过对两条链路的信号进行合并处理，从而获得分集增益，提升系统的性能。

This paper finished the argumentation, selection about schemes of telemetering digital diversity receiver, and established the design scheme of hardware and software through plenty of experiments on the key techniques.

通过对关键技术的实验研究，确定硬件设计方案和软件设计方案。

Moreover the combined performance of frequency diversity and time diversity can be gained by using time-frequency RAKE receiver.

接收端使用时频RAKE接收机，可以使系统具有频偏分集和时延分集的性能。
