<p>A communication system (100) utilizing a hierarchically modulated signal and method (200, 300) thereof are provided, wherein a receiver system (104) is configured to receive a hierarchically modulated signal. The receiver system (104) includes a receiver device (110) configured to receive the hierarchically modulated signal, which is a function of a time domain, and including a high priority data stream that has a single carrier type modulation, and a low priority data stream having data bits that are spread over a plurality of data symbols of a high priority data modulation. The receiver system (104) further includes a low priority processor device (114A), which includes an OFDM decoder (116) configured to convert the low priority data stream of the hierarchically modulated signal that is a function of the time domain to be a function of a frequency domain by utilizing a FFT, such that an output is emitted that is representative of the low priority data stream.</p> |
