ABSTRACT:
A forward error correction (FEC) system and method for use in a multipoint-to-point frame based synchronized transmission communication system in which data from users are sent in selected portions of data frames having coded symbols added thereto by encoders associated with each user. The number of bits per user assigned portions of data frames is established as an integer number of FEC code symbols. The interleaving depth is set equal to a multiple of the total number of code symbols sent by a user in a data frame. The encoders are synchronized such that all of the encoders start processing associated interleaving frames at the same time. In exemplary embodiments, the communication systems include DWMT and TDM communication systems.
