    Abstract Today, digital communication system should can transmite data or voice with high rate, have bandwidth eficiency, also have good performance in channel environtmen that always change because multipath fading. Because of that mutiple access CDMA that handles many users in same frequency and same time, can transmite data or voice with high rate also have wide bandwidth are used. In the CDMA, data signal corelated by pn code so that be random before transmite to air. It is very good because it can be reject noise, and very dificult to ilegal data snif, and have power eficiency. There are many pn code, one of them is gold, kasami, and walsh. Every pn code have unique characteristic, like have diference auto correlation value, and cross correlation value. It have many influence for the sistem. With compare pn code one another, we can know about sistem performance,and we know which pn best efective to used in the system. Walsh have best performance than another . The length of chip have big influence for system. More big the length more good the performance. Keyword : pn code,multiple access, cross korelasi,auto korelasi, walsh, gold, kasami
