1. A method comprising:

  • receiving a symbol vector on a plurality of channels;

    for each of the channels, estimating the channel and a normalized frequency offset of the channel;

    for each of the channels, determining a soft decision value of the symbol vector;

    executing an iterative recursive least squares RLS algorithm on each of the channels that approximates a covariance matrix of a composite noise vector of the received symbol vector until a minimum change to the estimate of the channel and the estimate of the normalized frequency offset is reached; and

    using the recursively estimated channel and normalized frequency offset across each of the channels, outputting a jointly decoded decision on the symbol vector.
