Systems and methods for multiple signal reception using receiver diversity
11764857 · 2023-09-19 · ·

Methods for improving multiple signal reception using receiver diversity in the context of a wideband radar and communications receiver. The method allows for improved signal reception as well as improved angle of arrival estimation. A first approach uses a method that improves angle of arrival estimation while using the standard diversity technique of selection combining. A second approach uses a method of equalization of the signal rather than equalization of the channel to both improve the signal SNR over standard selection combining and further improve the angle of arrival estimate over the first approach.
