Abstract

A signal receiver (120) includes an antenna interface (204) for receiving signals from an antenna (202) analog signal processing circuitry (208 a 208 b 208 c) coupled to the antenna interface (204) for processing the received signals to produce filtered signals sampling circuitry (210 a 210 b 210 c) to sample the filtered signals so as to produce digitized received signals a digital compensator (212 a 212 b 212 c) to receive the digitized received signals and compensate for non uniform group delay introduced by the analog signal processing circuitry (208 a 208 b 208 c) to produce compensated digitized received signals and a digital processor (214) to process the compensated digitized received signals so as to produce a result.
