Channel coding for satellite mobile channels [PDF]
International Journal of Satellite Communications, 1989 AbstractThe deployment of channel coding and interleaving to enhance the bit‐error performance of a satellite mobile radio channel is addressed for speech and data transmissions. Different convolutional codes (CC) using Viterbi decoding with soft decision are examined with inter‐block interleaving.

Key Generation Method Based on Multi-Satellite Cooperation and Random Perturbation
Entropy, 2021 In low-earth-orbit (LEO) satellite-to-ground communication, the size of satellite antennae is limited and the satellite motion trajectory is predictable, which makes the channel state information (CSI) of the satellite-to-ground channel easy to leak and ...

Coding for shared satellite channel communications [PDF]
IEEE Transactions on Communications, 2006 This paper investigates the design and performance of a two-user satellite communication system. Each user is independently encoded using a structured Turbo code with identical symbol interleavers. This permits Turbo decoding to be performed using the combined component code trellises, which provides significant gains over independent decoding.
