技術說明

本發明係揭露一種基於部分札德奧夫-朱序列之合作式多輸入多輸出正交分頻多工系統及其同步化方法。此系統係包含複數個傳送端及接收端。各個傳送端分別利用長度為V的子頻帶放置訓練訊號，並將其轉換為時域訊號。接收端接收時域訊號。傳送端由長度為V的倍數的一札德奧夫-朱序列中，取其任意區間的連續V個樣本放置於子頻帶中作為訓練訊號，使各個傳送端之訓練訊號在轉換為時域訊號及頻域訊號時，能夠相互分離，以降低接收端之相互干擾，增進系統同步化的效能。 A cooperative MIMO OFDM system based on partial Zadoff-Chu training sequence and a method thereof are disclosed, which comprise a plurality of transmitters and a receiver. Each transmitter is disposed with the training signal in the subband having a length of V, and converts which into the time domain signal. The receiver receives the time domain signal. Each transmitter extracts continuous V samples from any region of a Zadoff-Chu sequence having a length of a multiple of V and disposed which in the subband as the training signal. In this way, when being converted into the time and frequency domain signal, the training signal of each transmitter can be separated from each other to suppress mutual interference among training signals in both time and frequency domain and improve synchronization performance.
