Paper Abstract

In some scenarios of wireless communications, due to the fast change of channel information, it is very difficult to estimate the channel parameters in real time. This difficulty can be overcame by noncoherent communication techniques. In this paper, we propose a new class of unitary space-time codes for non-coherent wireless MIMO communications, aimed at improving the bit error rate performance and data speed of communication systems. This class of unitary space-time codes can be efficiently decoded using sphere decoder algorithms. A numerical approach is proposed for the optimization of signal constellation. Such coding techniques can be applied to the data transmission of wireless sensor systems.
