Abstract
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.
