摘要
直接序列扩频技术无论在军事通信还是民用通信都有广泛的应用。介绍了一种基于FPGA大规模可编程芯片的数字直接序列扩频接收技术,着重介绍了该数字接收机模型、PN码捕获及PN码同步技术,并且给出了该数字接收机的实际测量结果。
The Direct Sequence Spread Spectrum (DSSS)technology has been used widely in both military and civil communication.A flexible DSSS digital receiver based FPGA is introduced. Some key technologies, such as the model of DSSS digital receiver, the PN code detection, the PN code tracking, are analyzed.Finally, the measurement results are also shown.
