Abstract
In this paper, we present a decision feedback equalizer (DFE) that uses the quadrature components of 8-VSB signals in ATSC systems to mitigate multipath distortion efficiently. Unlike the conventional DFE structure for 8-VSB signals in which a real-valued feedback filter is used with real-valued decisions, the proposed DFE uses a complex-valued feedback filter with a complex-valued feedback sample generator. Due to the difficulty in analyzing a recursive system, we present a limited performance analysis on the proposed algorithm that a well-modeled feedback filter successfully cancels multipath channels with quadrature leakages in the absence of noise. For the performance comparison with conventional DFEs in realistic environments, we uses simulation methods.
