Abstract :
The new periodic binary codes, which compress to several chips, are searched in range of code length 50 by computers. We then found many new periodic binary codes with one for peak side-lobe level and zero for all side-lobe, which are different in M-sequences. Ratio of the peak side lobe level to the peak main lobe level for the new periodic binary codes is evaluated. Further, the Doppler characteristics and frequency band characteristics are obtained by using of MATLAB / Simulink. The results are compared with the M-sequences. It is assumed the results are better than these of the M-sequences.
