Abstract
A threshold estimate system includes a level quantizer, a correlation mechanism, and a threshold adaptation component. The level quantizer is configured to receive an input signal and to generate a quantization signal from the input signal according to one or more threshold levels. The correlation mechanism is configured to correlate the quantization signal with reference symbols to generate an output signal. The threshold adaptation component is configured to modify the one or more threshold levels according to the output signal and the input signal.
