For coherent detection, decoding Orthogonal Space-Time Block Codes (OSTBC) requires full channel state information at the receiver, which basically is obtained by channel estimation. However, in practical systems, channel estimation errors are inevitable and may degrade the system performance more as the number of antennas increases. This letter shows that, using fewer receive antennas can enhance the performance of OS-TBC systems in presence of channel estimation errors. Furthermore, a novel adaptive receive antenna selection scheme, which adaptively adjusts the number of receive antennas, is proposed. Performance evaluation and numerical examples show that the proposed scheme improves the performance to a great extent.

“…In this letter, we first extend the performance analysis of OSTBC under channel estimation errors in [12] [13] from the Alamouti scheme to a more general scheme. Then we propose an adaptive receive antenna selection scheme to maximize the post-processed SNR by selecting the optimal number of receive antennas.…”

“…From (13), it is clear that channel estimation errors lead to spatial intersymbol interference (ISI) if the estimated channel matrixĤ is not unitary (12). Another major task for coherent receivers is the carrier frequency offset estimation and correction.…”

We present a multiple antenna system for industrial, scientific, and medical (ISM)-band transmission (MASI). The hardware demonstrator was developed and realized at our institute. It enables multiple-input multiple-output (MIMO)-communication applications and is capable of transmiting arbitrary signals using 8 transmit and 8 receive antennas in parallel. It operates in the 2.4 GHz ISM-band. The hardware concept is introduced and some design specifications are discussed. Using this transmission system, we present some measurement results to show the feasibility of MIMO concepts currently under discussion. The applications include transmit and receive diversity for single carrier and OFDM as well as blind source separation (BSS) techniques

“…The performance analysis and evaluation of space-time transmit diversity over Rayleigh fading channels have been presented in [5] [6].The performance investigation of STTD in the versatile and more flexible Nakagami fading model has not been studied. From these backgrounds, a performance analysis of STTD over Nakagami fading channels was presented in this paper.…”

Space-Time Transmit Diversity (STTD) is an effective technique to combat radio fading in mobile communication systems. Previous work on STTD has been restricted to the idealistic case of perfect channel estimation and uncorrelated spatial fading. In this paper, the performance evaluation of STTD over correlated Nakagami fading channels is presented. The effects of imperfect channel estimation and correlation between different fading channels is considered and analyzed carefully. Simulation results are provided for STTD scheme over independent and correlated Nakagami fading channels with various fading parameters and correlation coefficients.I.
