Signature and Beamformer Optimization for MIMO-CDMA Based on the Mean Squared Error Criterion

Abstract

We consider the uplink of a CDMA system where the transmitters as well as the receiver are equipped with multiple antennas. Each user transmits a weighted form of its symbol through its transmit antennas. In this work, we adopt the system-wide mean squared error as the performance measure and propose an alternating minimization based iterative algorithm to… (More)
