This article examines uplink communication using wide bandwidth millimeter-wave orthogonal frequency division multiplexing and hybrid receiving. Building the beamformer and couplers for hybrid MIMO requires an understanding of channel information. Systems with (multiple-input multiple-output) functioning at millimeter waves (mm-Wave). The system’s spectral effectiveness is examined. When considering the channel model’s impacts with wide frequency and spatial bands with beam squint outcome brought on broadband effects is evident in finding study of simulations. Furthermore, it is made evident how the beam squint is affected by the bandwidth and subcarrier count.
