“…So the full-wave simulation is needed for adjusting SLL and D more precisely. In [13], a C-BFN with one input and three outputs has been designed for steering the beam by means of a passive phase shifter in the first layer of BFN. However, the scanning range is so much limited.…”

This article proposes CORPS beamforming network (BFNs) with both beam and null steering capability. All simulation results are presented for scannable mono‐beam configuration but it can be extended to the multi‐beam system. Complex inputs are optimised by means of the PSO algorithm to get the array factor with the desired characteristics that are side lobe level (SLL), directivity (D), and null depth. All sub‐blocks of the BFN are designed in the centre frequency of 2.4 GHz.

The channel sparsity is exploited by transforming the channel into an angular domain from the spatial domain at millimeter wave frequencies in Beamspace Multiple-Input Multiple-Output (B-MIMO) systems. Every beam in B-MIMO corresponds to an individual radio frequency (RF) chain, and thus, beam selection techniques can reduce the RF hardware complexity. RF chain limitation is needed for an ideal beamspace precoding scheme to attain good system performance across the entire bandwidth. New methods of beamspace channel estimation with a small amount of estimation error and low computational complexity are challenging in the beam domain due to the larger antenna arrays deployed. A novel beamspace processing technique to improve the direction of arrival estimation performance for different array configurations with improvement in system performance is desired in a 5G system. A detailed review of the B-MIMO system with its architecture and various beam selection techniques is presented in this paper. The scope of the work is elaborated by incorporating various existing beamspace precoding and channel estimation methods. The paper also presents various beamspace processing schemes for parameter estimation with a focus on the direction of arrival estimation performance.
