  • Performance analysis of transmit and receive antenna selection over flat fading channels 

    The paper considers two different antenna selection schemes for space-time coded systems over flat fading channels. First we explore antenna selection at the transmitter side based on the received signal to noise ratios. We then study the joint selection of receive and transmit antennas. Both schemes assume a slowly fading channel (i.e. quasi-static fading) and require some limited feedback from the receiver to the transmitter. By computing upper bounds on the pairwise error probabilities and ...

    We deal with transmit antenna selection for space-time coded (STC) systems over multiple input multiple output (MIMO) channels. Using pairwise error probability analysis and simulation results we show that transmit antenna selection based on received power levels does not reduce the achievable diversity order for full rank STCs. Initially we prove the results for Rayleigh flat fading channels and then we state our expectations for the case of frequency selective (FS) fading. In addition to the ...

    This paper studies performance of space-time coded (STC) systems with joint transmit and receive antenna selection over multiple input multiple output (MIMO) flat and frequency-selective (FS) fading channels. Specifically we first perform a pairwise error probability analysis over flat fading channels explicitly. Then we comment on our expectations for the case of FS fading channels. We show that the joint transmit and receive antenna selection based on received power levels does not degrade the ...
