Interference Cancellation for MIMO Systems Employing the Generalized Receiver with High Spectral Efficiency
Author:
Abstract: In this paper, we investigate the performan-ce in terms of symbol error probability (SEP) of multiple-input multiple-output (MIMO) systems employing the ge-neralized receiver with high spectral efficiency. In particu-lar, we consider the coherent detection of M-PSK signals in a flat Rayleigh fading environment. We focus on spectrally efficient MIMO systems where after serial-to-parallel con-version, several sub-streams of symbols are simultaneously transmitted by using an antenna array, thereby increasing the spectral efficiency. The reception is based on linear mi-nimum mean-square-error (MMSE) combining, eventually followed by successive interference cancellation. Exact and approximate expressions are derived for an arbitrary nu-mber of transmitting and receiving antenna elements. Sim-ulation results confirm the validity of our analytical meth-odology.
