Abstract:
Apparatus for generating and transmitting data in an available spectrum of frequencies suitable for use by a processing communication satellite comprising in combination:one or more earth terminals connected in order to provide data cells and a synchronizing burst timing signal; one or more encoders connected in order to group a predetermined number of the data cells with a selectable one of a predetermined first error correction code having a first code rate and a predetermined second error correction code having a second code rate to generate data bursts and to group the data bursts with synchronizing bursts timed in response to said synchronizing burst timing signal in order to generate data frames selected from a group of data frame types, said first code rate being a multiple of said second code rate; one or more modulators connected to modulate the data frames by a predetermined form of modulation to enable placement of the modulated data frames into a plurality of channels selected from a group of channel types having a plurality of channel rates definable in symbols per second; and one or more antennas connected to transmit the modulated data frames to the satellite over one or more beams with a predetermined form of polarization.
