Figure 5From: Performance of opportunistic fixed-beam spatial multiplexing in OFDMA uplinkCalculated spatial correlation in the chosen RB. Spatial correlation in the chosen RB of the fixed beam approach (BeamCorr) and the reference antenna approach (AntCorr) as a function of Laplace distributed RMS angle spread of impinging propagation paths. The plots are calculated for fixed 0° DOA in the direction of the BS antenna array normal, for Gaussian distributed DOA in a 120° sector, and for uniformly distributed DOA, over 360°. Antenna and beam patterns of Figure 3 were deployed.Back to article page
