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.
