Evolutionary Transmission Method for Layered SpaceTime Coding

This paper proposes a new transmission method for layered space-time coding according to the character of frequency diversity.Different antennas transmit different information with different frequencies at the transmitter.And at the receiver,different antennas receive different information from different transmission antennas,which means a transmission method of ″one to one″.The simulation results indicate that the method in this paper can improve the decoding efficiency for the receiver compared to the existing transmission method when decoding by the maximum likelihood.
