Abstract
Methods and corresponding systems for providing and demodulating an orthogonal modulated signal where demodulation includes separating a sampled orthogonal modulated signal into in phase and quadrature samples, deriving first and second equalizer coefficients based on corresponding in phase and quadrature samples and further, respectively, based on a first and second training sequence, programming a first plurality of equalizer filters with the first equalizer coefficients and a second plurality of equalizer filters with the second equalizer coefficients; and processing, after programming with first and second coefficients, the in phase samples and the quadrature samples through a first and second plurality of equalizer filters to provide demodulated symbols.
