通訊系統信號品質之估測

Abstract

本篇論文主要是探討即時通訊號品質之估測. 在本文中我們分析kozono的 干擾估測法則，並且提出新的估測法則，其估測值更準確其次考慮ＧＭＳ Ｋ鍵別器檢測的位元錯誤率，以機率密度分佈匹配找出ＭＬ估計 . 最後 我們利用數值模擬的結果來說明這些新發現的結果 ,並且考慮不同通道所 造成的影響. This thesis presents variable solutions for real-time CIR and BER estimations. The proposed CIR estimator is capable of offering reliable estimations under a variety of operation scenarios, namely, AWGN or Rayleigh fading with single or multiple interferer. On the other hand, our BER estimator is specifically designed for GMSK receivers using discriminator detection. The GMSK communication channel under consideration is a single-interferer, slow Rayleigh fading channel.
