The Pseudonoise Sequence Code and the Birth for Computer

WU Ming-jie,DU Tian-cang (College of information Engineering ,Beijing Institute of Petro-chemical Technology,Beijing 102600,China)  
Spectra expanding of spread-spectrum communication system make use of the spread-spectrum function,the typical spread-spectrum function is pseudonoise sequence code, the practical pseudonoise Sequence code must have the quality of randomness and sharp autocorrelation,it must have little cross correlation value and much set value ,it also demands of set balancing and being easy to achieve .Set m and set Gold pseudo-random code are widely applicated Spread-spectrum functions which can meet the qualification .This paper popularly introduces the theory ,property and conforming means of the two tatted code .It also introduces the method of obtaining,calculating and making up set volume by using computer from igional multinomial and recursion formula . The simple methode is convenient for engineering personnel.
