Abstract :
The objective has been to find memory-efficient coding/interleaving techniques and to accurately quantify their memory requirements. Toward this objective, convolutional interleaving, differential phase shift keying (DPSK) modulation, and various convolutional codes, Reed-Solomon codes, and concatenated convolutional and Reed-Solomon codes were evaluated by high-fidelity link simulations. Their interleaving memory requirements were derived as functions of data bit energy relative to channel noise-density for bit-error-rates of 10 -5. Interleaving delay requirements were also derived, and code selections with the smallest interleaving memory and delay requirements were identified
