Abstract :
A Postbeamformer Interference Canceler (PIC) is a beam space processor that processes the signals derived from an array of antennas by forming a signal beam and an interference beam. The paper presents a PIC processor using the orthogonal interference beam (OIB) and studies its performance by deriving the analytical results for the output signal to interference plus noise ratio (SINR) when an array is situated in the near field of broadband directional sources. A number of examples are presented to support the analytical results.
