Space-time Coding OFDM and Multi Beam Forming Combination Algorithm
Abstract：Aiming at multiple input and multiple output OFDM system,a simple and flexible space-time block codes and multidimensional characteristics of beam forming combination scheme is proposed,in order to make full use of the two order statistics of MIMO channel.In the scheme of space-time coding diversity at the same time which maximizes the system coding gain,space-time block codes is not affected by the actual number of transmit antennas selection,so it can be the diversity degree of coding gain and rate between the flexible compromise.Theoretical analysis and simulation results also show that,when the actual number of transmit antennas is greater than the number of antennas space-time codes,system coding gain with the actual number of transmit antennas increases approximately linearly increases,the transmit antenna array correlation is stronger with it.
