Packet-Error Probability Analysis lor Unslotted FH-CDMA System
摘要
对采用RS-(n
k)编码的非时槽FH-CDMA系统
分组区间内干扰用户数目是变化的.本文提出了一种简易模型
并找到了当干扰数目N>1时分组区间内的干扰分布与N=1时的内在联系
首次使用计算干扰状态概率平均的方法求得分组错误概率。通过比较
指出目前采用的上、下界及近似法效果欠佳。
Abstract
For unslotted FH-CDMA system with RS-(n
k) coding
the number of interfering transmissions varies throughout the packet duration. In this paper
we present a simple model and discover the essential relationship of interference distribution within the packet interval between N>1 and N=1
where N is the number of interfering transmissions. The packet error probabilitre’s obtained for the first time by averaging in the sense of probability over the distribution of all interference states. Furthermore
the lower bound and approximation methods used presently are shown to be inaccurate by comparison.
