Fig. 9From: mm-Wave channel estimation with accelerated gradient descent algorithmsEffects of sectorization. MSE vs M=M1=M2 for ULAs and various channel estimation techniques, when the average SNR is 10 dB when sectorization is used, with 6 (solid lines), 60 (dashed lines), and 180° (dotted lines).
