Despreading apparatus and method for CDMA signal

   
   

An apparatus and method for despreading a CDMA signal, wherein the apparatus performs a predetermined operation on a received CDMA signal and first and second codes to extract a pilot symbol and a data symbol from the received CDMA signal when the first and second codes are generated internally; and includes a correlation unit for performing operations on the respective inphase and quadrature components of the first code and accumulatively storing the results of the operations depending on first and second selection signals obtained from the first and second codes, a decimator for outputting individual accumulated values after individual results of the operation are separately accumulated a predetermined number of times by the correlation unit, and a symbol output unit for performing a predetermined operation on individual values output from the decimator to output the pilot symbol and the data symbol.
