Based on typical ADC quantizer and modified noise dither quantizer, this paper investigates the effects of several digitalizing parameters on the performances (processing gain and bit error rate) of DS/SS digital matched filtering/correlation and, the results of analysis and computer simulation are given. The problem about optimun soft limitation is studied. It's shown that the increase of quantizing bit number is move effective to improve the system performances compared with the use of noise dither. And it's found that the result of three-bit quantization is very near to that of infinite quantization. In addition, the effects of sampling interval as well as noise unity bandwidth are discussed. The results of study in this paper can be employed as use full theoretical bases for designing DS/SS digital matched filters/ correlators properly.

本文以典型的A/D变换量化器和改进型抖动噪声量化器为例,研究几个数字化参数对直接序列扩频(DS/SS)数字匹配滤波/相关性能(系统的处理增益和误比特率)的影响,给出理论分析及计算机模拟结果。用最优化方法研究最佳软限幅问题;指出增加量化比特数与引入抖动噪声相比能更有效地改善系统性能,而且只要采用三比特的量化就能使系统性能接近无穷量化的效果。文中还讨论了取样间隔以及噪声的归一化带宽对系统性能的影响。本文的结果可为合理设计直扩数字匹配滤波器/相关器提供必要的理论依据。

In this paper, the effects of quantizing bit number and sampling interval on the performance of DMF despreading circuit is investigated. It is found through simulation for DSSS that the result of 3-bit quantization is very near to the infinite quantization.In addition,the system BER of low sampling rate can be improved by the front-end processor(FEP)operation to be the same as that of high sampling rate while cost of hardware is largely reduced.

主要讨论了量化比特数和取样间隔对数字匹配滤波器 (DMF)解扩电路性能的影响 ,通过直扩系统 (DSSS)的仿真结果表明 :DMF的量化比特数取 3时 ,量化误差可忽略不计 (近似为无穷量化结果 ) ;而在低抽样率下依靠DMF的样值序列前端处理 (FEP)可以使系统误码率达到高抽样率的效果 ,而硬件代价却大大减小
