SPC12-4: Throughput Optimization for Continuous Flat Fading MIMO Channels with Estimation Error

In this paper, we consider single user throughput optimization problem for continuous flat fading channels of multiple-input multiple-output (MIMO) system. It is known that channel state information (CSI) at the transmitter enables significantly higher data rate for MIMO system compared to single-input single-output (SISO) system case. One of the widely used methods to obtain CSI is training based scheme. Putting more resource on training will give more accurate CSI, thus enabling higher data rate, but might decrease throughput because less resource is left for data transmission. The proposed mathematical framework enables us to find the optimal resource allocation between training period and data transmission period to achieve the highest throughput possible as a function of the number of antennas, Doppler spread, signal-to-noise ratio and computational complexity.
