| 摘 要： | 通过对多进制扩频系统的研究,仿真出几种不同进制下的误比特率曲线,与传统直接序列扩频进行了性能比较,并对采用不同信道编码的16进制扩频系统进行性能仿真,得出多进制扩频系统适合采用的信道编码。在抗单频干扰的通信模型下,仿真并分析了采用信道编码的16进制扩频系统的抗单频干扰能力,进一步说明多进制扩频具有良好的性能,适合应用于带宽受限的测控系统。 |

| Abstract: | Based on study on M-ary direct sequence spread spectrum system,several bit error rate curves for different carry are simulated,and the result is compared with the performance of traditional direct sequence spread spectrum system.Furthermore,16-ary direct sequence spread spectrum systems with different channel coding are simulated,and the most suitable coding is found.Finally,the anti-jamming ability of the 16-ary spread spectrum systems with channel coding is simulated and analyzed in the anti-jamming communication model.Results indicate that the M-ary direct sequence spread spectrum system has a good performance and can be applied to bandwidth-constrained measurement and control system. |
