Patent ID: 6996197

Claim:
An apparatus comprising: a first antenna outputting a first wideband signal; a second antenna outputting a second wideband signal; a first filter bank coupled to the first antenna, receiving the first wideband signal and outputting a first plurality of narrowband signals; a second filter bank coupled to the second antenna, receiving the second wideband signal and outputting a second plurality of narrowband signals; an interference suppressor receiving a first narrowband signal from the first filter bank and a second narrowband signal from the second filter bank and outputting an interference-suppressed signal based on the first and the second narrowband signals; synthesis circuitry receiving the interference-suppressed signal and a plurality of other interference-suppressed signals, and outputting a composite interference-suppressed signal based on the interference-suppressed signal and the plurality of other interference-suppressed signals; an FFT processor receiving the composite interference-suppressed signal and performing FFT processing on the signal; and wherein the first and the second filter banks operate continuously in a linear convolution fashion prior to FFT processing.
