An apparatus and method for processing a signal using a single correlator are provided. The apparatus may include a first storage unit storing satellite signal samples, a correlator receiving the satellite signal samples stored in the first storage unit in units of at least two satellite signal samples and performing correlation, and a controller storing the satellite signal samples received from an RF terminal in the first storage unit and controlling the correlator based on a predetermined control value. Accordingly, it is possible to ensure speed and performance even when tracking a plurality of satellite signals using a single correlator.

Apparatus and method for processing signal using single correlator

A correlation method of a code division multiple access receiver using mapping. Digital data with each signal composed of two bits are packed by a predetermined packing unit; blocking the packed data into data blocks according to a size corresponding to the repetition period of a C/A code. The packed data are recognized as an index in a correlation value mapping table having ICV and QCV mapped with each of different indexes and the ICV and the QCV are called from the correlation value mapping table. The called ICV and QCV are integrated according to the data blocks; and calculating a phase error of a carrier wave and a phase error of the C/A code using the ICV and the QCV according to the data blocks. A signal processing method is performed using the correlation method to correct phase errors.
