The analysis of simulation result indicates that the CDMA system has much more superior performance on noise-immune; the continuous processing in the part of signal modulation can not improve the efficiency of spectrum in CDMA system; under the situation , making sure that the proximity of the reliability of information transmission to the unsmoothed system, the power of the transmission can decline to 90.5% of the unsmoothed system, the bandwidth of -50dB will decline to almost one half of the unsmoothed system in spread spectrum and dispread spectrum by using continuous WALSH codes.

仿真及分析结果表明:CDMA系统具有更优越的抗噪声性能;信息调制部分的平滑化处理在CDMA系统中不会改善频谱的利用效率;运用平滑化WALSH码进行扩频和解扩时,在保证信息传输可靠性与非平滑化系统接近的情况下,能够将发射功率降低到非平滑化系统的90.5%,-50dB带宽减小到非平滑化系统的一半左右,这有利于降低对临近频段的干扰,提高频谱的利用效率。
