碩士 === 中正理工學院 === 電子工程研究所 === 88 === Abstract In this paper we design a PN sequence generator with a large linear complexity and long period by combining filter generator and combination generator. Computer simulation is performed to investigate the features of this PN sequence generator, such as linear complexity, partial correlation distributions, balance and the run length distributions of 1 and 0. From the simulation results, the PN sequence generator has a large linear complexity and a very long period. The numbers of 1 and 0 are nearly equal, and the distributions of partial correlation and run length of 1 and 0 are near that of ideal binary random sequence. So that the PN sequence generator is very suitable for the PN code used in secure DS-SS communication systems.
