技術說明

本發明揭露一多載波通訊系統，包括發射端設備與接收端設備；依照時間週期，該發射端設備處理多個原始符元並將之傳送至多個子載波通道，而該接收端設備則處理並偵測來自該多個子載波通道的多個接收符元。在傳送資料的一時幀中，每一個該子載波通道的初始三個該原始符元是給定的三個領航符元所構成的前言，其中每相鄰的三個該子載波通道的三個該前言構成一個前言單元，而該前言單元的所有領航符元以一個 3x3 的矩陣表示。當該前言單元的中心領航符元被正規化為 1 或 j 時，該矩陣為 (由上至下)：[-j -j -j]、[j 1 -j]、[-j j -j] 或 ：[1 1 1]、[-1 j 1]、[1 -1 1] 。本發明也揭露該多載波通訊系統的通道估測方法。 This invention discloses a multicarrier communication system that includes a transmitting equipment and a receiving equipment. According to a timing period, the transmitting equipment processes multiple original symbols for transmission on multiple subcarrier channels, and the receiving equipment processes and detects multiple received symbols from the multiple subcarrier channels. During a time frame of data transmission, the initial three of the original symbols for each of the subcarrier channels are three pilot symbols, forming a preamble. The three preambles of every adjacent three of the subcarrier channels form a preamble unit. All the pilot symbols of the preamble unit are expressed as a 3x3 matrix. When the center pilot symbol of the preamble unit is normalized to 1 or j, the matrix is (from top to bottom)：[-j -j -j], [j 1 -j], [-j j -j] or [1 1 1], [-1 j 1], [1 -1 1]. A channel estimation method for the multicarrier communication system is also disclosed.
