IEEE经典文章，CDMA PN序列差分捕获技术，文章内容详细，对学习和从事直接序列扩频同步捕获CDMA系统设计人员有很大帮助，推荐(New differentially coherent detectors for acquisition of direct sequence spread-spectrum signals are ntroduced. These detectors are alternatives to the noncoherent detectors that have been considered almost exclusively in the past. The proposed detectors are suitable for commercial code-division multiple-access(CDMA) systems which operate with a relatively large noise fl oor and provide a surprisingly large signal-to-noise ratio (SNR) improvement over the noncoherentdetectors of approximately 5 dB.)
