Abstract
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.
