Publisher and Date:(IEEE-INST Electrical Electronics Engineers Inc, 2008)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 ...
Performance of transmit and receive antenna selection in the presence of channel estimation errors Authors:
Publisher and Date:(IEEE-INST Electrical Electronics Engineers Inc, 2008)This letter considers the effect of channel estimation errors on the performance of space-time coded (STC) systems with transmit and receive antenna selection over quasi-static flat fading channels. By performing pairwise error probability analysis and presenting numerical examples we show that the diversity order achieved with perfect channel state information (CSI) is still achievable with imperfect CSI used both at the antenna selection and the space-time decoding processes. We note that our ...
Publisher and Date:(2010)In this paper antenna selection both at the transmitter and the receiver is proposed for space-time coded (STC) orthogonal frequency division multiplexing (OFDM) systems. Antennas for all-subcarriers or per-subcarrier are selected to maximize the signal to noise ratio (SNR) at the receiver which knows the channel state information perfectly and the transmitter only knows the indices of the selected antennas. The error performance is evaluated via simulations when space time block and concatenated ...
