Abstract:
Th is paper introduces the rea liza tion o f encoding and decod ing of G723. 1 by using OMAP5912, som e processes and princ ip les o f rea lizing d ig ita l frequency-hopping comm un ication equipment through the encoding and decod ing o f channe ls, as we ll as the interac tive commun ica tion o f ARM and DSP. Th is paper a lso introduces the theories o f frequency-hopp ing, o f channel encod ing, and the techn iques o f speech encoding, as w ell as the softw are and hardw are environment o f the TI OMAP em bedded system p la tform, frequency- em itting m odule, and CMOS ch ip o f speech encod ing and decod ing.
