A new vestigial sideband (VSB) digital transmission system has been developed for terrestrial and cable television broadcasting, and is currently being evaluated by the FCC's Advisory Committee on Advanced Television Service (ACATS) for adoption as the US standard. Initially, this new system must co-exist with the current analog NTSC television system. An important issue is the ruggedness and reliability of the RF data signal in real world environments. Receiver synchronization and signal processing play a vital role in reliable data decoding. > |
