Pseudo-Noise Sequences Based on M-sequence and Its Application for Communications

M 系列(最大長シフトレジスタ系列, Maximum-length shift-register sequence, M-sequence) は，スペクトル拡散通信における擬似雑音符号系列として有名であるが，通信の分野以外にも計測や制御の分野において，広く用いられている．本稿では，Ｍ系列の特徴及びＭ系列を基に構成される系列の構成法について解説している．特に，周期自己相関特性と相互相関特性を改善できる系列，受信符号同期タイミング捕そくと追跡に適した系列，符号分割多元接続法への適用を考えた系列について述べている．
