| Abstract: | Design and selection of spread spectrum code sequence is one of the key technologies of CDMA spread spectrum communication. The design of spread spectrum code sequence is constructing pseudo-random sequence which is possessed of different structure and good performances in order to satisfy the need of CDMA system. This article mainly introduces the basic principle, property and constructing means of m sequences, Gold sequences and Kasami sequences which are used in CDMA communication, also introduces its MATLAB and M language program realization and analysis of correlation, compares each characteristic and analyzes the applicability in deferent circumstances. |
| Keywords: | CDMA pseudo-random sequence correlation Matlab simulation |
