Inhalt:
In this paper, the problem of designing a multicarrier transceiver for single-link mmWave transmission is considered. Assuming hybrid beamforming with multiple data streams, it is shown how the common wideband analog beamformer can be optimized together with digital multiple-input, multiple-output precoders and receive equalizers which operate on per-subcarrier basis. For this purpose, two approaches originally constructed for narrowband systems are extended to wideband, and several simplifications for solving the optimization problems are made. Their evaluation is performed on a proposed statistical mmWave channel model and by utilizing measured channels.
