Abstract

自己相関関数のサイドローブが両端の点を除いて0になり,相互相関関数が一定のシフト範囲で0になる有限長系列の組ならびに,それを用いた準同期CDMAについて述べている.系列は部分系列の多重畳み込みで表され,高速畳み込みや高速相関のアルゴリズムを適用したディジタル信号処理が可能な構成となっている.PAM符号および2値被積分型符号を実数値有限長系列から作り,符号間干渉が殆んど無く局間干渉がない準同期CDMAを実験によって実証した.

This paper describes a set of finite-length sequences with zero side-lobe autocorrelation functions except at both ends and zero crosscorrelation functions within a specified zone, and their application to a quasi-synchronous CDMA system. The sequences are convoluted by multiple partial sequences, which enable to construct fast digital convolver or correlator. The quasi-synchronous CDMA system with a least intersymbol interferences and without interchannel interferences is verified by using PAM codes or two-valued integrand codes derived from the real-valued finite-length PN sequences.
