1. A communications device comprising: an antenna array for receiving different summations of source signals from a plurality of signal sources; a receiver coupled to said antenna array for receiving the different summations of source signals; and a signal separation processor coupled to said receiver for creating a matrix based upon the different summations of source signals, the matrix being defined by linear independent equations with fewer equations than unknowns, separating from the matrix a desired source signal from the plurality of source signals, determining an error rate associated with the desired source signal, and comparing the error rate to a threshold, if the error rate is not acceptable based upon the comparing, then modifying parameters associated with the matrix based upon a first set of parameter values and based upon at least one second set of parameter values, determining respective matrix quality factors associated with the first set of parameter values and with the at least one second set of parameter values, comparing the respective matrix quality factors for determining a preferred set of parameter values, and biasing the matrix with the preferred set of parameter values.
