A method and means for reducing multipath interference distortion in a time-division multiple access (TDMA) communications system is disclosed. A transmitting station (100) formats one or more equalizer synchronization words with a first user\s data word, time-multiplexes this formatted user message with at least one other user message, and transmits the combined signal. The receiving station (200) receives the transmitted TDMA signal, de-multiplexes the first user message from the other user messages, and equalizes the time delay spread characteristics of the data word portion of the first user message (or a stored version of such) in response to this de-multiplexing. Performing the adaptive equalization process more than once per user time slot provides an even higher data throughout for the system. Storing the first user message in a data buffer permits the adaptive equalization process to be performed in non-real time, thereby lowering the required signal processing data rate in any particular receiver.

A time division multiple access (TDMA) communication system comprising: a transmitting station including means for interleaving a plurality of first predetermined synchronization words with a plurality of first data words to form a first user message; means for multiplexing said first user message with at least one other user message to form a TDMA signal; means for transmitting said TDMA signal; and a receiving station including means for receiving said transmitted TDMA signal; means for de-multiplexing said first user message from said other user message of said received TDMA signal, thereby generating a TDMA control signal; and means for equalizing the time delay spread characteristics of the first user message data word portions of said received TDMA signal in response to said TDMA control signal at least the first time the plurality of predetermined synchronization word portions of said first user message are received.
