Patent ID: 8362952

Claim:
A radiolocalization receiver comprising: a correlation unit configured to process an RF signal from an RF interface to correlate the RF signal with a plurality of replica codes each having a determined code shift and a determined frequency; an incoherent accumulator configured to accumulate a series of coherent integration values and store these values in a plurality of incoherent integration memory locations; and a compression encoding unit configured to compress the content of the incoherent integration memory locations based in part on incoherent integration values previously stored in the incoherent memory locations, wherein the compression encoding unit is configured to determine absolute values of the content of stored coherent integration memory locations, wherein the absolute values of the stored coherent integration memory locations comprise absolute values of the stored coherent integration values or squares of the stored coherent integration values; wherein the compression encoding unit is further configured to generate increment values to be accumulated into the incoherent integration memory locations, and the compression encoding unit is further configured to subtract a current offset value from the increment value of each coherent integration and to store an accumulated offset of all the offset values subtracted during an incoherent integration operation.
