Description: 直接序列扩频Matlab程序
直接序列扩频通信可以有效地抵抗来自信道中的窄带干扰。在一个直扩通信系统中,扩频是通过伪噪声序列(PN)对发送的信息数据进行调制来实现的。在接收端,原伪噪声序列和所收信号的相关运算可将窄带干扰扩展到DS信号的整个频带,使干扰等效为幅度较低频谱较平坦的噪声；同时，将DS信号解扩,恢复原始信息数据。-Matlab procedures for direct sequence spread spectrum direct sequence spread spectrum communications can effectively resist the narrow-band interference from the channel. In a DSSS communication systems, spread spectrum pseudo-noise sequence through (PN) for sending information data modulation is achieved. At the receiving end, the original pseudo-noise sequence and the received signal related to computing can be extended to narrow-band interference signal DS the whole band, so interference is equivalent to a lesser extent than the flat spectrum of noise At the same time, the DS signal despreading and restore original information data.

Description: 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.
