Summary	This work will explore the performance of disadvantaged receivers in communications systems that utilize Multiple Input Multiple Output (MIMO), Space-Time Codes (STCs), and Orthogonal Frequency Division Multiplexing (OFDM). In some MIMO systems, the receiver uses a reliable feedback channel to convey channel state information (CSI) to the transmitter. The transmitter, in turn, can use this information to adjust its transmissions to optimize reception at the location of the receiver. This work seeks to analyze performance when this mechanism is flawed or there are multiple receivers, some not at the location for which the transmission has been optimized.
