6 Spectrum for extended hybrid mode The extended hybrid waveform is created by adding primary extended sidebands to the PM sidebands present in the hybrid waveform. Depending on the service mode, one, two, or four frequency partitions can be to the inner edge of each PM sideband. Each PM sideband consists of ten frequency partitions and an additional reference subcarrier spanning subcarriers 356 through 546, or 356 through 546. The upper primary extended sidebands include subcarriers 337 through 355 (one frequency partition), 318 through 355 (two frequency partitions) or 280 through 355 (four frequency partitions). The lower primary extended sidebands include subcarriers 337 through 355 (one frequency partition), 318 through 355 (two frequency partitions) or 280 through 355 (four frequency partitions). The subcarriers within primary extended sidebands are uniformly scaled the same amplitude scale factor, as the PM sidebands (see Fig. 33 and Table 18). a0, FIGURE 33 Spectrum of the extended hybrid waveform Service modes MP2 through MP4 – (The of the digital subcarriers is such that the total power of these carriers is 20 dB below the nominal power of the FM analogue carrier) TABLE 18 Extended hybrid waveform spectral summary service modes MP2 through MP4 – Subcarrier Number of Frequency Amplitude Frequency frequencies Subcarrier Sideband frequency partition scale span Comments (from channel partitions ordering centre) factor (Hz) (Hz) Includes 356 129 361 additional PM 10 A to to 69 041 reference a0 546 198 402 subcarrier 546 Includes 356 129 361 additional PM 10 B to to 69 041 reference a0 546 198 402 subcarrier 546 primary 337 122 457 extended 1 A to to 6 540 None a0 (1 frequency 355 128 997 partition) Lower primary 337 122 457 extended 1 B to to 6 540 None a0 (1 frequency 355 128 997 partition)
