A receiver for decoding encoded data transmitted by a transmitting station includes (i) sum and difference filters for filtering the encoded data and for providing corresponding sum and difference filtered outputs, (ii) first and second variable gain amplifiers for respectively controlling the sum and difference filtered outputs so as to provide corresponding sum and difference controlled filtered outputs that vary along a continuum in order to suppress co-channel interference and white Gaussian noise in the encoded data, and (iii) a Viterbi decoder for decoding the sum and difference controlled filtered outputs to recover uncoded data. |
