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.
