Title: High speed parallel burst modem

Abstract: A modem includes a high speed parallel processing transmitter, receiver and decoder. Each of the transmitting and receiving portions of the modem include a plurality of parallel processing channels that process data in a sub-band. Each of the processing channels can operate at a rate which is less than the overall rate at which data is processed. In each channel is a unique word sub-band filter and a data sub-band filter that are selectively enabled to filter data in the channel. The unique word filters in the transmitting portion of the modem are specifically tuned to make the unique word that precedes the data portion of a data burst easy to detect. In the receiving portion of the modem, the unique word sub-band filters are tuned to quickly detect the unique word. Once a unique word has been received, the data sub-band filters in the receiving portion of the modem are enabled in each of the channels to filter the data portion of a burst.
