Abstract
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.
