Modulated coded vector-TH preceding

In this paper, we propose a new kind of prccoding method, modulated coded vcctor-TH prccoding, to mitigate the channel intcrsymbol interference. The optimal design of the modulated code in vector TH precoding is presented. The coding gain of modulated coded vector TU precoding over conventional scalar TH precoding scheme is investigated in theory. Some simulation results arc reported, which show that the proposed modulated coded vector TH scheme can provide a considerable coding gain compared with the conventional prccoding techniques.
