An improved signal processing technique for developing a plurality of independent samples, particularly for use in a canceller system receiving interference from a plurality of sources. Each of a plurality of signal channels sample the environment from a plurality of interference source and provide inputs to a configuration of adaptive canceller loops. The loops are connected to provide independent samples of the interference environment from each of the signal channels. In a canceller system, each of the independent loop outputs are than used as an input to a canceller loop in the main channel to cancel interference in the receiving system. By using the independent samples, a receiving system can significantly increase interference cancellation and reduce the number of recirculations or iterations required. Patent
