本文所要解决的的问题是十进制的转换。即将十进制转换为任意的r(r是大于一的正整数)进制问题。因为要解决一个问题必须要对其进行解剖,所以首先对问题进行详细的描述对题目有充分的了解,其次是对问题的详细分析,主要包括对问题的解的分析以及对问题的解的结论的分析。第三主要是建立问题的解决方案,虽然解决问题的方法有很多种,本文主要采用即:把一个十进制数转换成非十进制数(基数记作R)分成两步.整数部分转换时采用“除R取余法”;

Abstract-The effect of the companding process on QAM signals has been under investigation for the past several years. The compander, included in the PCM telephone network to improve voice performance, has an unusual affect on digital QAM data signals which are transmitted over the same channel. The quantization noise, generated by the companding process which is multiplicative (and asymmetric), degrades the detectability performance of the outermost points of the QAM constellation more than that of the inner points. The combined effect of the companding noise and the inherent white gaussian noise of the system, leads us to a re-examination of signal constellation design. In this paper we investigate the detectability performance of a number of candidates for signal constellations including, a typical rectangular QAM constellation, the same constellation with the addition of a smear-desmear operation, and two new improved QAM constellation designs with two-dimensional warpi
