There is growing interest in using millimeter wave (mmWave) communication for fifth generation (5G) wireless systems because of the large bandwidth available in these frequencies. To overcome the higher path loss at mmWave bands, highly directional beamforming using large-scale, or massive, multiple-input multiple-output (MIMO) systems is critical. In this scenario, the problem of channel estimation becomes challenging due to the substantial training overhead needed to sound all possible beam… CONTINUE READING
