- Abstract
- An adaptive code-rate scheme for ka-band satellite syatem which adapts the level of coding to overcome rain-induced signal fade is presented. It is based on a pragmatic code, and can decode the QPSK and TC-8PSK signals using a single Viterbi decoder. The optimal parameters for implementation through computer simulations are determined. The adaptive channel coding algorithms described in this paper may be used for high-speed satellite communications to compensate the rain-attenuation. © 2003 IEEE.
