“…As a special case of this work, it is straightforward to consider the situation where the interferers have equal powers and there are fewer interferers than antenna elements. Hence, the approximate densities and outage probabilities discussed in [13] can be made exact. In [13] approximate BER values are also derived for a range of modulations.…”

“…Hence, the approximate densities and outage probabilities discussed in [13] can be made exact. In [13] approximate BER values are also derived for a range of modulations. In situations where the conditional probability of error is an exponential function of the SINR (i.e., DPSK) the exact BER is given in [14], [15] for the general case.…”

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.

Beamforming for inter‐relay interference reduction in MIMO‐aided two‐path successive relaying

To effectively reduce the inter-relay interference (IRI) in two-path successive relaying, two beamforming schemes are proposed in this paper, utilizing multiple-antenna relay nodes. Specifically, the two cooperation nodes perform receive combining of the source signal and transmit beamforming of the relayed signal alternately in the successive relaying process. As a result, the IRI between them can be effectively suppressed, thanks to the additional degree of freedom provided by the multiple-input multiple-output inter-relay channel. In the first beamforming scheme, the source-to-destination signal-to-interference-plus-noise ratios (SINR) of separate paths are maximized with approximation, leading to a minimum variance distortionless response beamformer under the high SINR condition. To further improve the system performance, noting that the received SINRs of the two paths have impact on each other due to the mutual coupling of the beamformers, the sum of mean squared errors from these two transmission paths is minimized in the second scheme. Based on this performance criterion, a suboptimal beamformer design is developed numerically through cyclic minimization of the sum of mean squared error cost function. Simulation results demonstrate the superiority of both proposed beamforming schemes in terms of symbol error rate and the achievable system rate, in particular, at high IRI levels.
