A forward error correction (FEC) method is provided that operates in a multiple access format, such as, e.g., a Time Division Multiple Access (TDMA) format. An FEC transband central station and a plurality of FEC transband remote stations transmit data and corresponding error correction data therebetween during time frames. The time frames are divided into in-band time slots during which the traffic data is transmitted and out-of-band time slots during which the error correction data may be transmitted. The FEC transband remote stations that are assigned to the out-of-band time slots are efficiently and dynamically adjusted during communication.
