| Abstract: | This paper analyzes the balance property of Z 4 sequences and discusses in detail the correlation distribution of the generalized odd correlation of the 4 phase spread spectrum sequences based on Z 4 codes.It also compares the 4 phase spread spectrum sequences based on Z 4 codes with other 4 phase spread spectrum sequences with respect to the correlation properties such as the correlation peak and the correlation mean square.The results show that the 4 phase spread spectrum sequences based on Z 4 codes have good correlation properties.And it may be a candidate for the 4 phase spread spectrum sequences in DS/CDMA systems. |
