 note = {In this paper, the spread spectrum code hopping (CH) system, which has some analogy to frequency hopping systems, is described. The CH system has robustness to code interference that restriction of kinds of PN matched filters (MFs) will cause. The mean acquisition time is shown by theoretical analysis and computer simulation. The acquisition rate results under a single code interference, which seriously affects direct sequence systems, and an asynchronous two-user channels are obtained. Moreover, using theoretical analysis and computer simulation, the bit error rate (BER) performance under single code interference is evaluated. It is shown that CH systems perform better than conventional ones under single code interference., Copyright notice. c1995 IEICE All rights reserved.　"The Spread Spectrum Code Hopping System" Takeshi ONIZAWA,Takaaki HASEGAWA IEICE TRANSACTIONS on Fundamentals of Electronics, Communications and Computer Sciences, 1995  Vol.E78-A No.7  pp. 795-804 許諾No.07RB0055., text, application/pdf},
