Summary: In this thesis, the performance of DSSS system, which is one of the SS systems, was analyzed for some digital modulation techniques. For this analyze, Rayleigh channel was used. Performs diagram were formed. DSSS systems spread spectrum of data signal by multiplexing with special codes which have special auto-correlation and cross-correlation and despread it in receiver. Because of this property DSSS system is infused less by interference. These codes call Pseudo-Noise (PN) sequence. PN sequence, which has different length, was used to show the effect of length of PN sequence.
