基於最小位元錯誤率準則之無線通訊接收機

Abstract

MBER準則被發現能比傳統的MMSE準則更有智慧的調整線性接收機的權重而達到較小的錯誤率。 本論文不僅對MBER準則及其目標函數的最佳化方法(牽涉到非線性規劃)做深入的研究，也對可適性演算法的設計下了一番功夫。我們還應用MBER準則低錯誤率的特性，發展出一套能比傳統方法更降低其上傳功率的功率控制方法。 在後面幾個章節的最後(第三章~第五章)，我們皆以模擬來驗證我們的方法比傳統的方法會有更好的效果，而以討論來說明這些現象發生的原因。

MBER criterion was discovered that it can adjust the weight of the linear receivers more intelligently than the traditional MMSE approach to achieve the small Bit-Error-Rate. This thesis not only research on MBER criterion and the optimization method of the cost function for MBER criterion(involve in nonlinear programming), but also take effort on designing the adaptive algorithm for it. Moreover, we develop an uplink power control method which can decrease the uplink power than the traditional method by exploiting the property of low BER for MBER criterion. On the back of last few chapters(ch3~ch5)，we verify that our methods has better performance than the traditional ones by showing the simulation results, and discuss how this happened.
