IEEE 802.11p訊號接收與數位訊號處理器實現之探討

Abstract

在本篇論文裡，我們探討在IEEE 802.11p標準下訊號的接收，在我們所設計的接收器裡包含了同步、循環前綴的移除、快速傅立葉轉換、通道估計、基頻解調、解交錯器、維特比解碼器、解攪亂器。我們著重分析同步及通道估計問題。我們使用MATLAB Simulink做模擬，並在數位訊號處理器(DSP)上實現同步及通道估計的演算法、分析它們的效能。

In this thesis, we study the signal reception of IEEE 802.11p standard. In our considered design, the receiver consists of synchronization, cyclic-prefix removal, fast Fourier transform (FFT), channel estimation, baseband demodulator, deinterleaver, Viterbi decoder and descrambler. We put emphasis on the analysis of synchronization and channel estimation block. We simulate our design with MATLAB Simulink and implement the synchronization and channel estimation on digital signal processor (DSP) to analyze the performance.
