Pilot Based Space-Time Transmission Scheme for Large MIMO System

In this paper, we investigate a pilot based space-time transmission scheme (STTS) for large multiple input multiple output communication system. We design pilot based STTS to estimate the channel state information using orthogonal pilot sequences and the concept of null space. The signal is detected using maximum - likelihood decoding method. The approximate expression of symbol error rate of proposed system is obtained using moment generating function of instantaneous received signal-to-noise ratio.
