The research on length reconstructing of multiphase sequences

In CDMA systems,the realization of multiple access can be achieved by the special sequences with correlation demand,if the spread spectrum sequences are longer, the ratio between the main peak value and the side peak value of the auto-correlation function is bigger,then the sequences can reach the correlation demand of the spread spectrum code in systems.The multiple phase sequence based on Suehiro's method has the direct ratio characteriste between its length and its phase numbers, its length is finite and the sequences (don't) adapt to application in practice.So,the pseudo-periodic sequences are introduced and the length of on multiphase sequences will be changed by reconstructing,then the feasibility of the multiphase sequences used in practice is improved.
