1. A system for decoding signals received from a plurality of channels having correlated, effective noise, the system comprising:
a lead channel selector for determining a lead channel in the plurality of channels;
a first decoder for decoding signals in the lead channel to form a first decoded codeword;
a subtraction unit for determining an estimate of effective noise on the lead channel by subtracting the first decoded codeword from the signals received in the lead channel; and
a second decoder for decoding signals in another channel in the plurality of channels using the determined estimate of effective noise on the lead channel to form a second decoded codeword.
