This paper deals with the modeling of the statistical distribution of the effective gain of terminals. This incorporates both the characteristics of the antenna’s radiation pattern in the situation of use, and the characteristics of the local propagation environment. A frequency-wise and frequency-correlated log-normally-distributed effective-gain model is proposed as a standard model of wide – although not universal – validity. This is done mainly for the sake of simplicity and ease of use. This model is tested in a few exemplary cases of measured and simulated terminals, using a subset of the WINNER channel model for the local propagation.

We present a user-scheduling scheme for multiuser multiple-input–multiple-output (MIMO) systems with random unitary beamforming (RUB) in this paper. The new scheme, which is termed as adaptive beam activation based on the conditional best beam index feedback (ABA-CBBI), requires low average feedback load by imposing a feedback threshold on the users’ signal-to-interference-plus-noise ratio (SINR) and suffers less multiuser interference by only activating those beams requested by at least one user.

This code uses the output from either make_zeta_u.c file or make_zeta_v.file i.e. it uses the velocity data at any z-level specified by zlevel1. Furthermore, this code filters the velocities, plots the filtered and raw signals at certain specified locations and then creates maps of the velocity time series
