ABSTRACT:
A receiver for demodulating multiple digital modulation formats including vestigial sideband (VSB), quadrature amplitude modulation (QAM), and offset QAM (OQAM). The receiver includes a timing recovery circuit that produces accurate timing information for each modulation format and a signal processor for adaptive equalization and quantization of each modulation format. The adaptive equalizer is a passband equalizer that performs blind equalization using a feed forward equalizer and a decision feedback equalizer.
