Abstract
An approach for decoding a substantially orthogonal code, such as a CCK code, based on its trellis diagram is provided. Compared to the conventional decoder based on codeword correlation, the unconventional decoder here has the advantage that it can work together with a decision feedback equalizer without suffering from the error propagation effect of the equalizer. In other words, the unconventional decoder makes joint decision feedback equalizer and decoder workable, which in turn enables reliable transmission of a signal encoded by a substantially orthogonal code over a multi-path channel.
