MULTIPLE RESOLUTION MODE ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEM AND METHOD

摘要

The disclosed embodiments relate to a system and method for processing communication signals. An exemplary method (400) of processing a received orthogonal frequency division multiplexing (OFDM) broadcast signal (48) having a frequency spectrum (130) comprises demodulating the OFDM broadcast signal (48) over a subset of the frequency spectrum to create a first demodulated signal component corresponding to a first signal component (126), the first signal component being representative of a lower resolution version of a second signal component (128), and providing data corresponding to the first demodulated signal component.
