| 摘要: |
| 随着移动通信的迅速发展, 码分多址技术受到越来越多的关注。为了提高系统的抗干扰性能, 在CDMA系统中采用了M阶正交信号。通过分析采用M阶正交信号的DS-CDMA 系统基带接收信号的统计性能, 文中得出了多址、多径干扰下系统的误码率计算公式, 并详细分析了系统的抗干扰性能。 |

| Abstract: |
| With the development of the mobile communication, the CDMA techniques has attracted more and more attention. To reduce interference, M-ary orthogonal signaling is employed. In this paper, the performance of the DS-CDMA system with M-ary orthogonal signaling is analyzed in terms of the bit error probability by analysing the statistics of the received baseband signal. . |
