Statistics of the Effective Massive MIMO Channel in Correlated Rician Fading
Jens Abraham, Pablo Ramirez-Espinosa, Torbjörn Ekman
Massive MIMO base stations use multiple spatial diversity branches, which are often assumed to be uncorrelated in theoretical work. Correlated branches are considered seldom since…
Local Diversity and Ultra-Reliable Antenna Arrays
Jens Abraham, Torbjörn Ekman
Ultra-reliable low-latency communication enables new use cases for mobile radio networks. The ultra-reliability (UR) regime covers outage probabilities between and $10^{-…
Fading Margins for Large-Scale Antenna Systems
Jens Abraham, Torbjörn Ekman
Mobile phone operators have begun the roll-out of 5G networks, deploying massive MIMO base stations. Commercial product ranges start with 16 independent radio chains connected to a…
Power Inversion of the Massive MIMO Channel
Jens Abraham, Torbjörn Ekman
Channel hardening characterises the diminishing influence of small scale fading on large scale antenna systems. The effective massive MIMO time domain channel is introduced and app…
Measured Channel Hardening in an Indoor Multiband Scenario
Golsa Ghiaasi, Jens Abraham, Egil Eide +1
A study of channel hardening in a large-scale antenna system has been carried out by means of indoor channel measurements over four frequency bands, namely 1.472 GHz, 2.6 GHz, 3.82…
Minimum Mean Square Error Estimation Under Gaussian Mixture Statistics
John T. Flam, Saikat Chatterjee, Kimmo Kansanen +1
This paper investigates the minimum mean square error (MMSE) estimation of x, given the observation y = Hx+n, when x and n are independent and Gaussian Mixture (GM) distributed. Th…
