1. A system for preprocessing desired and undesired signals of a multiple signal environment comprising:

  • a plurality of independent channel means for receiving signals from a multiple signal environment and providing a plurality of output signals;

    an output terminal coupled to provide one of said independent channel means output signals as an unaltered first independent preprocessed auxiliary sample; and

    second means coupled to said output terminal and each of the remaining independent channel means for sequentially decorrelating each remaining independent channel means output signal to form a plurality of independent preprocessed auxiliary samples as a first circulation, said second means being constructed to decorrelate each independent channel means output signal of the sequence from a prior preprocessed auxiliary sample to form one of said plurality of independent preprocessed auxiliary samples wherein said first independent preprocessed auxiliary sample forms said prior preprocessed auxiliary sample for decorrelating the first independent channel means output signal of the sequence and each preceeding independent preprocessed auxiliary sample of the sequence forms said prior preprocessed auxiliary sample for decorrelating the next succeeding independent channel means output signal of the sequence.
