Non-binary forward error correction (FEC) coding in conjunction with M-ary hyper phase-shift keying (MHPSK) is considered in order to improve the robustness of a satellite communications uplink. MHPSK is a spectrally efficient modulation technique that uses four orthonormal basis functions to increase the distance between different symbols in the signal space. Spectral efficiency and probability of...
The Joint Tactical Information Distribution System (JTIDS) is the communication terminal of Link-16. JTIDS is a hybrid direct sequence/frequency-hopping spread spectrum system and features Reed-Solomon codes for channel coding, cyclic code-shift keying for 32-ary symbol modulation, minimum-shift keying for chip modulation, symbol interleaving, chip sequence scrambling and random jittering for transmission...
Cyclic code-shift keying (CCSK) is the baseband symbol modulation scheme used by Joint Tactical Information Distribution System (JTIDS), the communication terminal of Link-16. Since CCSK is non-orthogonal, an analytic evaluation of its performance in terms of probability of symbol error is nontrivial. In this paper, an analytic upper bound on the probability of symbol error of CCSK is derived for...
Forward error correction (FEC) coding in conjunction with M-ary hyper phase-shift keying (MHPSK) is considered in order to improve the robustness of a high spectral efficiency satellite communications link. MHPSK is a spectrally efficient modulation technique that uses four orthonormal basis functions to increase the Euclidean distance between different symbols in the signal space. Spectral efficiency...
This paper demonstrates the application of binary convolutional coding applied to the bandwidth efficient, constant envelope modulation developed by Resnikoff and Tigerman. The modulation waveform and phase form are presented with the corresponding bit error performance expression for uncoded M-ary modulation. Probability of information bit error performance analysis is provided for M-ary modulation...
