Methods, software and apparatuses for decoding received delayed path signals are described. A receiver receives a signal via different paths with relative delay, e.g., on the same frequency channel. The signal is sampled at at least one sample per symbol. A channel estimator determines channel coefficients associated with the channel over which the signals were transmitted. A processor selects samples that include a dependence on a particular symbol being decoded and computes an error metric for each possible value of the particular symbol, for combinations of hypothesized future symbol values on which the selected samples depend, and for single values of previous symbols on which the selected samples depend. Error metrics calculated for each symbol are stored in memory. A soft symbol is generated based on said signal samples from the sampler, the channel coefficients and estimates of symbols computed.
