Abstract: A burst mode time division multiple access (TDMA) data processing system can determine burst time plans (BTPs). The burst mode TDMA data processing system can receive burst mode time division multiple access (TDMA) data. The burst mode TDMA data can be distributed among processors based on the BTPs. The distributed burst mode TDMA data can be demodulated and decoded the using the processors and the demodulated and decoded burst mode TDMA data can be output.

Abstract: Systems and methods are provided for channelizing. A first stage can provide a WOLA filter bank that can apply a single multiplier resource to perform window weighting for multiple WOLA filter banks. The first stage can remove mixer-based post FFT adjustment and provide equal functionality with a particular modification of tuning mixers at inputs of second stage FIR paths. The first stage can include a variable decimation, using a particular implementation of variable sample block size.

Abstract: A method and a satellite gateway for minimizing an impact of a noise floor variation in a spot beam satellite system. A demodulator processes digitized signals from multiple channels. Digitized signals are automatically gain controlled by respective automatic gain control components associated with respective channels. Automatic gain controlled digitized signals are downconverted and provided to a burst processor. The burst processor processes each downconverted signal and provides, with respect to each downconverted signal, an automatic gain control estimate, a code rate, and an inroute number to a processor component. The processor component determines an average automatic gain control value for each inroute, provides automatic gain control references to the respective automatic gain control components, and periodically sends noise map information to satellite terminals served by the satellite gateway. In some embodiments, the automatic gain control values are biased according to corresponding code rates.
