Beamforming Techniques Hybrid Beamforming... Page 1 | Page 2 | clear all; close all; clc; Nt = 64; Nr = 16; NtRF = 4; NrRF = 4; At both the transmitter and receiver ends, there are four RF chains only for a hybrid beamforming system. Alternatively, every 16 antenna elements on the transmitter side is connected to a single RF chain, while every 4 antenna elements on the receiver side are connected to a single RF chain. Mixers, amplifiers, and other critical wireless communication components make up the RF chain. Now, in the case of hybrid beamforming, there can be four different data streams between the transmitter and receiver, as both sides have four RF chains, each of which is accountable for a separate data stream. For Analog Beamforming: All 64 Tx antenna elements create a beam or focus the resultant correlated signal spread from adjacent antennas to a particular direction. Similarly, it may be used for beam...
