Abstract:
1. A cooperative multiple-input multiple-output system based on a partial Zadoff-Chu sequence, comprising: a plurality of transmitters located at various locations, exclusive subband to dispose the partial Zadoff-Chu sequence as training signals Z(k) in frequency domain, and converting the training signals Z(k) into time domain signals; and a receiver, arranged for receiving the time domain signals; wherein, each transmitter obtains V consecutive samples of any region from a complete Zadoff-Chu sequence having a length equal to a multiple of V and disposes the samples in the exclusive subband and uses the samples as the training signals Z(k), such that when the training signals Z(k) of each transmitter is converted into the time domain signal and a frequency domain signal, the signals are able to be separated from each other to reduce mutual interference at the receiver to enhance the performance of system synchronization; wherein, V is a length of the exclusive subband in frequency domain; and wherein, the partial Zadoff-Chu sequence comprises a portion of consecutive samples of the complete Zadoff-Chu sequence.
