Uplink transmission and reception techniques for a processing satellite including one or more earth terminals 400 connected to receive ATM data cells. One or more encoders 418 are connected to coordinate four data cells with an error correction code to generate data bursts and to coordinate the data bursts with synchronizing bursts to generate data frames. One or more modulators 420 are connected to modulate the data frames by frequency division multiple access modulation to enable placement of the modulated data frames into a plurality of channels. One or more antennas 406 transmit the modulated data frames to a satellite 100 over 48 beams with various forms of polarization. In satellite 100, a receiving multibeam antenna and feed 106 responds to one or more beams of radiocarrier signals having one or more forms of polarization. One or more demodulators 138 demodulate the radio carrier signals into data frames from various channels including a plurality of channel types. One or more decoders 146 decode data bursts and synchronizing bursts from the data frames and decode four data cells from the bursts using error correction code.
