Square Peg Communications Inc. (SPCI) has completed an evaluation of a C-band global aeronautical broadcast system using transponder EIRPs varying from 26 to 29 dBW. The following were evaluated:
0 dB/K G/T C-band aeronautical antennas for major wide bodied aircraft types
aeronautical fading channel effects
dual-rate modulation and coding
acquisition, demodulation and decoding algorithms
link layer protocol for point-to-multipoint distribution of multiple data streams on a single carrier
link budget analysis assuming single saturated carrier per transponder operation and adjacent satellite interference coordination
transmitter and receiver performance specifications.
