Abstract :
The new perfect complete generalized complementary orthogonal code group, which has perfect aperiodic auto-correlation function and cross-correlation function, is constructed. Two new methods, which are based on Schweitzer´s concept and theory of overlap and reuse, are adopted to improve the code efficiency. There is no adjacent cell interference for the ideal auto-correlation function and cross-correlation function between different cells, which is confirmed by simulation.
