Patent ID: 8406277

Claim:
An apparatus comprising: a correlation unit to correlate a signal associated with a radiolocalization system with a plurality of replica codes and provide an output signal comprising a code-stripped signal, each replica code having a determined code shift and a determined frequency; an integration unit to accumulate data from a biased output signal in a plurality of correlation taps, at least one correlation tap corresponding to a determined replica code having a determined combination of code shift and frequency of the replica code, the integration unit comprising a first stage with one or more accumulation units, at least one accumulation unit being programmable to accumulate correlation data relative to a correlation tap, and a second stage programmable to accumulate data from one or more of the one or more accumulation units; and an encoding unit to encode the code-stripped signal in a sequence of numbers that are either non-negative or non-positive to provide the biased output signal.
