A Method to Generation and Simulation of PN Sequence in MATLAB

Spread spectrum communication is a new theory and modulation technique, and different from the conventional communication system. A good correlation property and large linear period of Pseudo-random sequence is the basis of spread spectrum communication systems intern CDMA (code division multiple access communication systems). Out of several techniques to implement direct sequence spread Spectrum (DSSS), one technique PN (pseudonoise) sequence/ code which is referred as the high rate digital code is generated on MATLAB. This generated m-sequence is then converted into polar format. Finally, in this paper we examine autocorrelation of PN sequence and compares the simulated autocorrelation with theoretical measured autocorrelation function at different value of N.
