Embodiment Construction
[0043] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0044] 1. Establish, analyze and process MIMO space-time system model
[0045] 1. Establish MIMO space-time system model
[0046] Create a system with N t transmit antennas and N r A MIMO space-time system with two receiving antennas. Each frame signal transmitted by the transmitting antenna is composed of training sequence, cyclic prefix and data. The channel is a flat and slow-varying Rayleigh fading channel. Assuming continuous N f The channel state experienced by the frame signal is the same, that is, a data block consists of N f frame composition, such as figure 1 shown.
[0047] The training sequence in the wireless communication system is divided into a time domain orthogonal training sequence, a frequency domain orthogonal training sequence and a code domain orthogonal training sequence. In the space-time system model establi...
