Abstract

A Postbeamformer Interference Canceller, PIC, is essentially a single-channel noise canceller. Two beams are formed; one in the target direction and another in the interference direction. The interference direction beam is processed with a tapped delay filter before being subtracted from the target beam to yield the system output. A detailed analysis of PIC is presented in the paper. The performance which can be achieved with PIC is shown to depend critically on the input signal to interference ratio and the tapped delay line length.
