| Abstract: | Currently, a multi-channel PCM sound satellite broadcast transmission mode has beendeveloped in Japan which adopts PCM multi-chanel high voice quality TDMA method. The papermainly describes the quasi instantaneous companding technique, bit error control technique, bit inter-leave and interference-adding technique adopted by the sound transmission mode. These techniquesare simulated by computer in C~( ) language. |
