Abstract
An interleaver memory access apparatus of a CDMA system including an interleaver memory for storing code symbols to be transmitted; a shift register unit for simultaneously receiving 18 bit code symbols from the interleaver memory and outputting the 18 bit code symbols in three sets of 6 bit code symbols; an index decoding unit for decoding the 6 bit code symbols outputted from the shift register unit and generates a Walsh bit index; an address generator and control logic for controlling an access operation of the interleaver memory and the input and output operation of the shift register unit and the index coding unit; and an orthogonal modulator for outputting 64 bit Walsh codes based on the Walsh bit index outputted from the index decoding unit.
