Abstract
Techniques are described for demodulating burst communications, such as for demodulating satellite beam-hopping communications in a demodulator of a very small aperture terminal (VSAT) satellite receiver. The demodulator includes a front-end and a sample/symbol domain processor. The front-end is configured to selectively operate in either of an adaptive mode or a freeze mode. During demodulation, the sample/symbol domain processor detects start of superframe (SOSF) and end of superframe (EOSF) locations to determine where each dwell time and non-dwell time begins and ends. During at least a portion or each dwell time, the front-end is set to operate in adaptive mode, in which the front-end uses feedback control from the sample/symbol domain processor to continuously adapt to timing and frequency of the received burst transmission. During at least the duration of each non-dwell time, the front-end is set to operate in freeze mode, in which adaptation of the front-end is frozen.
