1. A receiver comprising:

  • a bank of correlators for receiving a received signal that is a linear combination of a set of non-orthonormal signature signals that has undergone some distortion; and

    a set of correlating signals;

    whereinthe bank of correlators cross-correlates the received signal with the set of correlating signals to produce a vector output, andthe set of correlating signals is orthogonal and is determined by minimizing the least-squares error between the set of correlating signals and the set of signature signals.
