Reduced complexity precomputation for decision feedback equalizer

摘要: Techniques for reducing the complexity and power requirements of precompensation units, as well equalizers, devices, systems employing such techniques. In an illustrative method providing high speed equalization, comprises: obtaining a channel response that presents trailing intersymbol interference in signal having sequence symbols from symbol set; determining distribution threshold values unit corresponding to said with deriving reduced set distribution; implementing decision feedback equalizer reduced-complexity values. related set, initial unit; filter converts into modified response, improved includes fewer distinct or spacing between at least some adjacent values; distribution.
