1. Apparatus comprisingmeans responsive to a stream of input data for generating a sequence of coded modulation signal points representing that data, said coded modulation signal points being generated from a code having built-in diversity,means for transmitting the coded modulation signal points to a receiver, with at least the coded modulation signal points which provide said diversity being transmitted using respective different frequencies,means for detecting ones of the coded modulation signal points received by the receiver that are likely to have been subject to strong interference, andmeans for performing soft decision decoding responsive to the received values of said ones of the coded modulation signal points, other than said detected ones of the coded modulation signal points likely to have been subject to strong interference, to form decisions as to the values of the transmitted coded modulation signal points.
