| 摘 要： | 提出了一种可以有效地实现用户高数据率传输的卷积编码正交扩频多码ＣＤＭＡ系统．此系统对于用户传输的高速率数据首先进行串－并转换，变换后的低数据流再进行卷积编码，然后再进行正交序列扩频调制．各支路扩频信号用同一载波进行调制发送．对此系统在加性高斯噪声信道的性能计算和数值结果进行了分析．

| Abstract: | A convolutional encoded orthogonal sequence multicode CDMA system is analyzed so as to transmit high rate data. For the high rate data of transimters' serial to parallel converted at first, and then the low rate data streams are convolutionally encoded and spreaded spectrum by a set of orthogonal sequence, all low branch data streams use a singal carrier. the performance of the system in AWGN channel is calculated, and numerical result is analyzed. |
