This means that semi-unitary frequency flat precoding and combining are sufficient to achieve the maximum spectral efficiency when there is not too much scattering in the channel. It also motivates the use of techniques such as compressive subspace estimation as an alternative to estimating the full...
Hybrid Precoding and Combining for Millimeter Wave/Sub-THz MIMO-OFDM Systems with Beam Squint Effects consider the problem of hybrid precoding and combining for wideband millimeter wave (mmWave) and sub-terahertz (THz) MIMO-OFDM systems with beam squint ... Q Wan,J Fang,Z Chen,... - 《IEEE...
Several approaches have been proposedfor precoding/combining in such architectures [3]–[5]. In [3],the sparse structure of the mmWave channel is exploited toformulate the precoding problem and then the OrthogonalMatching Pursuit (OMP) algorithm is used to approximatethe optimal unconstrained (...
Coherent combining of the two transmitted layers is then achieved at the receiver antenna in the UE. For NT=2 CRS antenna ports and r=2, these are the three specified precoding matrices in the LTE codebook W=121001,12111−1,1211j−j The first matrix simply indicates to transmit one ...

The requirements of low cost and power consumption for future wireless systems can be met by combining these two technologies. In this paper, we formulate the problem of jointly designing the hybrid precoding at the base station (BS) and the phase shifts at the RIS for both single-cell and ...
