A simple space-time coding technique for wireless communication systems

Modern telecommunication systems are piqued for/by high data rate to improve reception quality. High data rate can be, naively, achieved using increased bandwidth. Since bandwidth is a limited resource, we study a method of maximizing system performance by improving data rate of communication systems via diversity gain. This followed from multiple input multiple output (MIMO) scheme provided by space-time block coding (STBC). The new method uses Hadamard matrices to form a quasi-orthogonal STBC (QO-STBC) code structure that is void of some off-diagonal terms in the detection matrix thus maximizing the system performance. The code structure significantly improves the MIMO system performance consequent on the analytical provisions.
