技術說明

本發明係揭露一種具備資料相關性疊加訓練機制的通訊系統及其通訊方法。此系統係利用放置於資料相關性疊加訓練序列之前的預編碼模組，經由預編碼矩陣對資料執行預編碼。此預編碼矩陣為N×N的單式矩陣，並由Q×Q的預編碼子矩陣構成，Q為區塊長度N除以通道長度。此預編碼矩陣將資料均勻地分佈在頻域上，且任二組經由預編碼矩陣預編碼後之資料必定相異，以使接收端能夠有效地辨識傳送端傳送之資料，並且降低接收端之運算複雜度。 The present invention discloses a communication system with data-dependent superimposed training mechanism and a communication method thereof. The system performs precoding on data through a precoding matrix by a precoding module before the data-dependent superimposed training sequence. The precoding matrix is a N×N unitary matrix, which is constructed by Q×Q precoding sub-matrix. Q is the block size N divided by the channel length. The precoding matrix can achieve full frequency diversity. Any two sets of data precoded by the precoding matrix must be different from each other, such that the receiver can effectively identify the data transmitted from the transmitter and the computational complexity of the receiver is reduced.
