A system for broadcasting the same data in concatenated convolutional coded (CCC) form from a network of 8-VSB amplitude-modulation transmitters operated with different radio-frequency carrier waves assigns the coded data to time-interleaved ones of time slots that are universal throughout the network. Therefore, a mobile/handheld (M/H) receiver with a single frequency-agile tuner can provide frequency-diversity reception of the time-interleaved data in CCC form. Alternatively, an M/H receiver with two tuners is used to provide frequency-diversity reception of the time-interleaved data in CCC form. The system for a network of 8-VSB AM transmitters that broadcast the same data in CCC form can further provide for each 8-VSB AM transmitter to make repeated transmissions of data in CCC form, to facilitate iterative-diversity reception of those transmissions by M/H receivers. |
