Abstract (in Japanese) (See Japanese page) 
(in English) Pseudonoise sequences for spread spectrum communication or radar system are desired to be the finite-length sequences with impulsive autocorrelation function. Self-orthogonal finite-length sequences so called Huffman sequences have impulsive autocorrelation function except at both ends. This paper describes transmission of two-valued code from a real-valued self-orthogonal finite-length sequence by two-value integrand coding. The two-valued code constructed by a sequence of length 65 and magnitude below 2 and 16-division integrand codes is integrated and smoothed by low pass filters, to be converted to PAM (pulse amplitude modulation)code. Experiments show correlation outputs of low side lobes.
