1. A receiver comprising:

  • a correlation demodulator, the correlation demodulator receiving one or more predetermined signals and noise, the demodulator having plural correlators, each correlator cross correlating the one or more predetermined signals and noise with a signal and outputting a correlation signal, and the demodulator providing a set of correlation signals a, the correlation signals a having a first covariance matrix; and

    a correlation shaper, the correlation shaper receiving the set of correlation signals a and transforming the correlation signals a to a second set of signals b, equal in number to the set of correlation signals a, the second set of signals b having a second covariance matrix and the second covariance matrix is proportional to an identity matrix on at least a subspace of the second covariance matrix.
