“…The case of correlation on the side with the maximum number of antennas was explored in [15], where the authors upper and lower bounded the SNR using a linear transformation of Hermitian quadratic variables. Later, [16] extended the analysis to the doubly correlated Rayleigh fading channels. However, analytical results were derived only for dual 2 2 MIMO configurations.…”

This paper introduces some novel upper and lower bounds on the achievable sum rate of multiple-input multiple-output (MIMO) systems with zero-forcing (ZF) receivers. The presented bounds are not only tractable but also generic since they apply for different fading models of interest, such as uncorrelated/correlated Rayleigh fading and Ricean fading. We further formulate a new relationship between the sum rate and the first negative moment of the unordered eigenvalue of the instantaneous correlation matrix. The derived expressions are explicitly compared with some existing results on MIMO systems operating with optimal and minimum mean-squared error (MMSE) receivers. Based on our analytical results, we gain valuable insights into the implications of the model parameters, such as the number of antennas, spatial correlation and Ricean-factor, on the sum rate of MIMO ZF receivers.Index Terms-Correlated fading, multiple-input multiple-output (MIMO) systems, sum rate, zero-forcing receivers.

In this paper, the multiple-input multiple-output (MIMO) system with a precoder is considered in the transmit-correlated Rayleigh channels. We specifically target the MIMO system employing the minimum mean square error receivers. Based on random matrix theory, we first present a direct and generalized formulation for deriving a probability density function (PDF) of the signal-to-interference-plus-noise ratio (SINR). Then, we derive the accurate closed-form SINR PDFs for a small number of transmit and receive antennas. Based on the SINR PDFs, tight closed-form approximations of the symbol error rate (SER) are derived. Our analysis suggests that the SER approximations can be used to accurately estimate the error probabilities or as a useful tool for the system design. . 본 논문에서는 최소평균제곱오차 (minimum mean square error, MMSE) 수신기를 갖는 SM 시스템을 대상으로 한 다 [2] .모바일 통신 및 유도무기 점검을 위한 MIMO

“…However, performance provided by linear receivers are quite dependent on the correlation between the signatures of the intended and interfering signals, e.g., spatial correlation between the channel gains in the MIMO systems [16]. As shown in (9), mobile OFDM systems resemble virtual MIMO systems where the intended and interfering signals have spatial signatures of c m , and {d n }.…”

In OFDM systems, mobility induced Doppler spreading distorts the orthogonality among the subcarriers, and results in intercarrier interference (ICI) which degrades the reception quality. In this paper, we investigate how ICI can be mitigated by using multiple receive antennas. In this context, by using Taylor series approximation of the time-varying channels, we derive minimum mean-squared error (MMSE) linear combining scheme for Doppler compensation. Motivated by lower complexity, we develop new combining schemes, i.e., Simple Doppler Compensating Combiner (SDCC) and approximated Zero Forcing (aZF) combiner, based on approximation of MMSE combining. We show that by new combining schemes, the Doppler tolerance of mobile OFDM systems can be increased significantly with respect to conventional maximum ratio combining (MRC) with a moderate increase in computational complexity. Furthermore, we show that the proposed linear combining schemes can be combined with existing single-antenna ICI mitigation methods, forming a Hybrid Doppler compensation method that obtains higher mobility tolerance.
