Precodings for transmission rate increasing in MIMO single carrier block transmissions

In wireless communication systems, multi-input multi-output (MIMO) wireless, which exploits the spatial diversity, is known as a cost-effective solution for high data rate. In the MIMO systems, the linear precoder and decoder, which is the joint processing at the transmitter and receiver sides and decomposes the MIMO channel to the parallel flat fading subchannels, is introduced to achieve performance improvement. In this paper, for the MIMO block transmission systems, we propose a precoding method aiming at increasing the transmission rate. The effect of the proposed method is proved theoretically and its validity is demonstrated by computer simulations.
