| 摘 要： | 提出一种基于软件无线电的多路中频数字化DS-CDMA空地数传系统设计方案.发射通道将信息分解成16路并行码后用相互正交的PN码分别扩频,再由多通道数字上变频器AD6623完成BPSK调制,最后进行中频合成.接收通道在对16路接收信号并行解扩后再合并得到原始信息.

| Abstract: | A Multiplexer IF digital air-ground data communication system is presented.The symbols transferred by the transmitter are divided into 16 parallel streams that spread spectrum by 16 orthogonal PN sequences.Each DSSS signal is modulated to a digital BPSK IF stream separately at the same frequency by one AD6623's TSP channel,and all of them are combined in summation.The receiver de-spreads each DSSS signal separately and recoveries the symbols. |
