Abstract
A cooperative multiple-input multiple-output system based on partial Zadoff-Chu sequences and a synchronization method thereof are disclosed, and the system comprises a plurality of transmitters and a receiver. Each transmitter's training signal is disposed in a subband having a length of V, and the training signal is converted into a time domain signal. The receiver receives the time domain signals of the cooperating transmitters. Each transmitter extracts V successive samples from any region of a Zadoff-Chu sequence having a length equal to a multiple of V and the samples are disposed in an exclusive subband as the training signal. When the training signals of cooperating transmitters are converted into time and frequency domain signals, the training signals of all the transmitters are separated from each other to suppress mutual interference in both time and frequency domains and to improve the performance of synchronization.
