Abstract: A method and apparatus for mitigating the beam squint effect in a wideband wireless communication device involving a phased antenna array. Time delay units are operated in series with phase shifters to apply phase shifts to signals fed to or received from antenna elements. The array may be subdivided into sub-arrays each associated with its own time delay unit, and with each antenna element associated with its own phase shifter. The phase shifters are operated to compensate for location mismatch between time delay units and antenna elements, and also to compensate for practical limitations of the time delay units, such as length and quantization limitations.

Abstract: Some aspects of the present disclosure relate to detection of a Phase Hit and, upon detecting the Phase Hit, determining the magnitude and location of the Phase Hit. Detecting the Phase Hit may involve comparing a phase offset difference for successive pilot symbol to a detection threshold. Determination of the detection threshold may involve a Neyman-Pearson binary hypothesis testing (NP-BHT) approach. Once the magnitude and location of the Phase Hit are known, data symbols received after the location may be processed to remove the magnitude of the Phase Hit.
