Summary:The power of the respective codes used by the first and second error detection/correction circuitry are such that the coded bit error rate of the first data stream is more closely matched to the coded bit error rate of the second data stream. A hierarchical QAM system allows the transmission of different sources by embedding the relative constellation points. The hierarchical QAM transmitter encodes the first data stream using a code having a first detection/correction power and encodes the second data stream using a code having a second detection/correction power.
