METHOD FOR GENERATING BINARY SPREAD CODE HAVING ZCD AND APPARATUS THEREFOR

摘要

PURPOSE: A method for generating a binary spread code having a ZCD(Zero Correlation Duration) and an apparatus therefor are provided to generate a spread code in which a side lobe around the peak of an autocorrelation value and a cross correlation value are zero during a uniform time interval which is less than (N/2+1) chips. CONSTITUTION: A binary autocorrelation preferred pair code generating unit(100) expands a code period to a code in which a period is N chips and generates a binary ZCD preferred pair code in which a zero correlation characteristic is maintained. A binary autocorrelation duration code set generator(170) shifts the generated binary ZCD preferred pair code and generates a ZCD code set.
