| Abstract: | The principle of a digital sound receiver for receiving TV signals from the DBS BS-2a is given. The NICPCM-4DPSK multi-plexing technique and the blocks of the receiver, including NICPCM, error-correcting and detecting coding, bit interleaving, scrambling, interpolation, synchrocontrol, carrier recovery bit synchronization and frame synchronization are briefly described. Field tests show that the operation of the system is stable and the performance is good. |
