Abstract

We investigate simplified, yet mismatched, receivers for SC-FDMA MIMO transmission currently employed in the 3GPP LTE-Advanced uplink. The receivers are based on frequency domain equalization and time domain detection. Rates achievable by those mismatched receivers with arbitrary input alphabets are derived in terms of generalized mutual information. The results allow to compare the impact of certain simplifying receiver assumptions under various conditions, such as spatial correlation or channel length. In addition, the results could be used to adjust the transmission rate according to the receiver detection metric.
