Millimeter wave (mmWave) MIMO will likely use hybrid analog and digital precoding, which uses a small number of RF chains to reduce the energy consumption associated with mixed signal components like ...

Precoding is a signal processing technique that modifies the phases and amplitudes of wireless signals to combat channel distortion and optimize the quality and reliability of data transmissions. It ...

Finally, we propose a low-complexity algorithm to realize SIC-based hybrid precoding, which can avoid the need for the singular value decomposition (SVD) and matrix inversion. Complexity evaluation ...
