P P ACQUISITION METHOD FOR PRECISION CODE BASED ON MEMORY ARRAY AND RECEIVER FOR ACQUIRING PRECISION CODE BASED ON MEMORY ARRAY

摘要

A method for acquiring a P-code based on a memory array includes dividing an input signal received by a receiver into a plurality of received codes, storing the FFT operation value for each of the plurality of received codes in a first memory column, Dividing the continuous local code generated by the local code into a plurality of local codes, storing the FFT operation value for each of the plurality of local codes in a second memory column, Determining a value of the sum of the FFT operation values for a pair of neighboring at least one local code in a successive local code, and determining the value of the sum of the FFT operation values for a pair of the at least one local code corresponding to each of the plurality of received codes Performing a correlation operation on the sum of the correlation values and superimposing the result of the correlation operation, The result includes the step of determining the value of the synchronization point, based on whether more than a threshold value.
