| dc.description.abstract | 基於LTE的通訊標準下，對於隨機存取前置訊號的偵測，我們提出了相關性範數偵測接收器，在這個系統底下，我們針對單載波分頻多重存取技術發展了一個簡化模型，並根據這樣的條件下應用了奈曼皮爾森準則以及廣義概似比檢定設計出相關性範數偵測接收器。相較於相關性峰值偵測接收器，我們提出的相關性範數偵測接收器在雷利衰退通道下以及弱萊斯衰退通道的漏失偵測機率表現較好，兩者的系統複雜度也相當接近，最後，本研究所提出的相關性範數偵測接收器，在不同的通道模型下，亦有穩健的系統表現。 | zh_TW |
| dc.description.abstract | Random access procedure is an important aspect for the terminal to connect with the base station. Also, the detection performance is a crucial issue in Physical Random Access Channel (PRACH). However, the performance of preamble detection in correlation peak detection (CPD) algorithm is sensitive with the channel model. When Rayleigh fading channel is adopted, the performance of CPD receiver degrades. In this thesis, based on the generalized likelihood ratio test (GLRT) principle and the Neyman Pearson (NP) criterion , the correlation norm detection (CND) algorithm is proposed. It is shown that the proposed method provides a robust performance in the preamble detection. | en |
