A robust receiver for multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) systems is proposed. We are interested in the scenario when only a limited number of pilot symbols in both time and frequency domains are available. For this scenario, perfect channel state information is impossible to obtain and the receiver suffers from channel estimation errors. To overcome...
We present a general upper bounding framework for the average bit error probability (ABEP) of generalized spatial modulation (G-SM) over correlated Rayleigh and Rician channels. Our approach is applicable to any multiple-input multiple-output (MIMO) configuration and linear modulation alphabet. The framework also incorporates possibly correlated Gaussian channel estimates. The ABEP with perfect channel...
We present a general framework for the analysis of the effects of channel estimation errors on the average bit error probability (ABEP) of spatial modulation over correlated Rayleigh and Rician channels. The proposed approach is useful in obtaining the upper bound on the ABEP exactly for M-ary PSK constellations and with a very close approximation for M-ary QAM constellations. The framework is applicable...
