Exact Performance Analysis of Optimum Combining With Multiple Interferers in Flat Rayleigh Fading

Abstract

Abstract-This letter provides a comprehensive overview and extension of recent results on outage probabilities and bit-error rates (BER) for optimal combiners in the presence of multiple interferers and additive noise. Desired signal and interferers are subject to flat Rayleigh fading and all channels are independent. In addition to summarizing previous work, this letter also derives the BER for a wider range of modulations than previously considered. We show that previous approximate results on the equal power interferer case where the number of interferers is less than the number of antenna elements can be made exact in a straightforward way. Finally we extend previous work on the single and double interferer case to the general case of arbitrary numbers of interferers.

Exact dual-user macrodiversity performance with linear receivers in flat Rayleigh fading

“…This subject D. A. Basnayaka is supported by a University of Canterbury International Doctoral Scholarship. has been well-studied in the micro-diversity case [9], [10], [11], [12] where there may be distributed sources, but the receive antennas are closely spaced. The performance metric of interest is the SINR/SNR distribution since this also leads to results for bit-error-rate (BER), symbol-error-rate (SER), outage probabilities and capacity, etc.…”

“…In independently distributed Rayleigh channels, basic results in statistics have been used to great effect [9], [10]. In the presence of correlation, if a Kronecker correlation structure is assumed, there are also many results available [13], [14], [15], [16].…”

On the secrecy performance of transmit-receive diversity and spatial multiplexing systems

“…This leads to an increase in the data rate. While several key performance metrics of spatial multiplexing MIMO systems, e.g., error probability, outage and ergodic capacity, have been extensively studied in the literature (Chen & Wang, 2007;Smith, 2007;Ordóñez et al, 2007;Kumar, Caire & Moustakas, 2009;Jiang, Varanasi & Li, 2011), little is known about the secrecy performance of these systems in the fading MIMO wiretap channel. The second objective of our work is to fill this knowledge gap by providing a relevant secrecy outage probability characterization.…”

Performance Analysis of Dual-User Macrodiversity MIMO Systems with Linear Receivers in Flat Rayleigh Fading

“…We focus on the baseline case of a flat fading Rayleigh channel, where the links are all independent but have different SNRs due to the geographical separation. This subject has been well-studied in the micro-diversity case [11], [12], [13], [14] where there may be distributed sources, but the receive antennas are closely spaced. The performance metric of interest is the SINR/SNR distribution since this also leads to results for bit-error-rate (BER), symbol-error-rate (SER), outage probability and capacity, etc.…”

“…The difficulty in analyzing macrodiversity systems is that there is no coherent methodology currently available to handle the type of channel matrices that occur. In independently distributed Rayleigh channels, basic results in statistics have been used to great effect [11], [12]. In the presence of correlation, if a Kronecker correlation structure is assumed, there are also many results available [16], [17], [18], [19].…”
