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: the paper I uploaded was submitted in my DSP2 class. The paper discusses the results of the simulation based on the paper of Zatman on "How Narrow is Narrowband?" It investigates the second eigenvalue parameter of the received signal that determines its "narrowbandness". Zatman explains that once the second eigenvalue of the signal autocorrelation matrix rises above the noise floor, the signal BW becomes non-zero.-the paper I uploaded was submitted in my DSP2 class.
