摘要:
本文叙述了丽音(NICAM-728 )多声道彩电广播中数码伴音的发送和接收过程工作原理及设计要点,揭示和初步分析了其中最先进的核心部分:数字数据的扰乱及解扰、交错及去交错、差动正交相移键控( DQPSK)及多路信号解码器、数-模变换器等,可供有关厂商开发及改进新产品时参考。
Abstract:
The working principles and design key-points for transmitting and receiving the mufti-channel digital sound television broadcast are described and given. Among the advanced core parts, the data energy dispersal scrambling and unscrambling, bit interleaving and disinter leaving, differential quadrature phase-shift keying modulator and demodulator, mufti-channel encoder and decoder are revealed and analyzed preliminarily.
