On the Capacity of MIMO-MAC in Rician channel [PDF]
The Egyptian International Journal of Engineering Sciences and Technology, 2021 The information theoretic limits for the single user MIMO (Nt×Nr) communication channel are well established in literature for different scenarios of channel types and channel state information (CSI) availability.

Joint User Identification and Channel Estimation Over Rician Fading Channels [PDF]
IEEE Transactions on Vehicular Technology, 2020 This paper considers crowded massive multiple input multiple output (MIMO) communications over a Rician fading channel, where the number of users is much greater than the number of available pilot sequences. A joint user identification and line-of-sight (LOS) component derivation algorithm is proposed without requiring a threshold. Based on the derived

On the capacity of MIMO Rician broadcast channels [PDF]
2008 IEEE International Symposium on Information Theory, 2008 In this paper, a downlink communication system, in which a base station (BS) equipped with M antennas communicates with N (N Gt 1) single-antenna users, in a Rician fading environment is considered. The asymptotic (in terms of the number of users) sum-rate capacity of the system, as well as the capacity-achieving strategies, are derived.

Location-based beamforming for Rician wiretap channels [PDF]
2016 Australian Communications Theory Workshop (AusCTW), 2016 We propose a location-based beamforming scheme for wiretap channels, where a source communicates with a legitimate receiver in the presence of an eavesdropper. We assume that the source and the eavesdropper are equipped with multiple antennas, while the legitimate receiver is equipped with a single antenna.

Measured User Correlation in Outdoor-to-Indoor Massive MIMO Scenarios
IEEE Access, 2020 The performance of a multi-user multiple-input multiple-output (MIMO) system is mainly determined by the correlation of user channels. Applying channel models without spatial correlation or spatially inconsistent channel models for performance analysis ...

Energy detector performance in Rician fading channel [PDF]
Serbian Journal of Electrical Engineering, 2013 In this paper we analyzed the problem of detection of unknown signals in the Rician fading channel. A closed-form expression for the probability of detection is derived, followed by the numerical results. The analysis was extended to the case of

Monotonicity Results for Coherent MIMO Rician Channels [PDF]
IEEE Transactions on Information Theory, 2005 The dependence of the Gaussian input information rate on the line-of-sight (LOS) matrix in multiple-input multiple-output coherent Rician fading channels is explored. It is proved that the outage probability and the mutual information induced by a multivariate circularly symmetric Gaussian input with any covariance matrix are monotonic in the LOS ...
