Abstract: Selective radiation of radio frequency (RF) reference beams in a wireless communications system (WCS) based on user equipment (UE) locations is disclosed. The WCS may include a radio node that communicates RF communications signals in a coverage area via RF beamforming. Thus, the radio node is required to periodically radiate a number of RF reference beams in different directions of the coverage area to help UEs to identify a best-possible RF beam(s).

In this regard, the radio node can be configured to selectively radiate a subset of the RF reference beams based on a determined location(s) of the UE(s) in the coverage area, thus making it possible to reduce computational complexity and power consumption of the radio node.

Abstract: Various embodiments provide for deep learning-based architectures and design methodologies for an orthogonal frequency division multiplexing (OFDM) receiver under the constraint of one-bit complex quantization. Single bit quantization greatly reduces complexity and power consumption in the receivers, but makes accurate channel estimation and data detection difficult. This is particularly true for OFDM waveforms, which have high peak-to average (signal power) ratio in the time domain and fragile subcarrier orthogonality in the frequency domain. The severe distortion for one-bit quantization typically results in an error floor even at moderately low signal-to-noise-ratio (SNR) such as 5 dB. For channel estimation (using pilots), various embodiments use novel generative supervised deep neural networks (DNNs) that can be trained with a reasonable number of pilots. After channel estimation, a neural network-based receiver specifically, an autoencoder jointly learns a precoder and decoder for data symbol detection.
