摘要：
A broadband satellite communications system comprises forward error correction (FEC) encoder/decoder, interleaver/deinterleaver, puncturing/de-puncturing, scrambler/descrambler, bit to symbol mapping/de-mapping devices, modulator/demodulator, transmit and receive filter; operating in a time-division multiple access (TDMA) system where information is sent in a burst-by-burst fashion during the assigned time slot; supporting diverse traffic types such as voice over internet protocol (VOIP), control messages (DACCH) and keep alive burst (KAB) during silence period and multiple data rates.
