Abstract
A device for generating a spreading code in a CDMA communication system is disclosed. In the device, an ML (Maximal Length) sequence generator generates an ML sequence according to a generator polynomial of an ML sequence having a length 2 −1 and a given initial value, and reloads the initial value whenever an ML sequence having a length shorter than the length 2 −1 is generated, to repeatedly perform an operation of generating the ML sequence. A mask selector including first and second masks having a given offset, selects the first mask in an ML sequence period of the desired length and selects the second mask in the other period. A modulo-2 adder adds an output of the ML sequence generator and an output of the mask selector to generate the spreading code, and truncates the ML sequence upon receipt of the second mask.
