Adaptive decorrelating sidelobe canceller

A canceller system having four or more signal sources with correlated components uses signals from three of the signal sources to cancel correlated components from the signal of the fourth signal source. The canceller apparatus includes a main cancellation channel with serial cancellers and a prepro...

Zusammenfassung:	A canceller system having four or more signal sources with correlated components uses signals from three of the signal sources to cancel correlated components from the signal of the fourth signal source. The canceller apparatus includes a main cancellation channel with serial cancellers and a preprocessing arrangement of cancellers made up of M auxiliary channels each having M-1 serial cancellers. Each of the M auxiliary channels outputs is decorrelated from each other auxiliary channel output and each is provided as an input to one of the main channel serial canceller.
