Optimal joint design of orthonormal real valued short time block code and linear transceiver for next generation home

The main contribution of this paper is to propose an optimal joint design of an orthonormal real valued short time block code and a linear transceiver for multi-input multi-output (MIMO) wireless digital communication systems in next generation home. Firstly, a relaxed zero forcing condition governing the relationship between the short time block code and the linear transceiver is imposed via a Karhunen Loève transform (KLT) approach. The relaxed zero forcing condition guarantees that there is no transmission error under a noise free environment. Secondly, the linear transceiver is optimally designed via the orthogonal Procrustes approach. In particular, the transmission power gain is minimised subject to a specification on the ratio of the signal gain to the noise gain as well as to the relaxed zero forcing condition. Computer numerical simulation results show that our proposed optimal joint design of the orthonormal real valued short time block code and the linear transceiver can significantly improve the performances of MIMO wireless digital communication systems in next generation home.
