摘要
Ｂｌａｕｍ－Ｒｏｔｈ码是一种能纠多个相位突发错误和擦痕错误的最优码。解决了Ｂｌａｕｍ－Ｒｏｔｈ码的周期分布问题，这也是到目前为止能求出其周期分布的唯一一类非循环码。还指出了Ｂｌａｕｍ－Ｒｏｔｈ码中周期最大的码字在跳频序列设计中的应用，一般循环码的周期分布问题已经在文献［１］中被解决了，但是对非循环码而言，此问题还远未解决。
Blaum-Roth code is a new family of codes for correcting multiple phased burst er-rors and erasures. The period distribution problem for Blaum-Roth code is solved.Thus thefirst,up to now,closed period distribution formulation for a non-cyclic code is found.Blaum-Roth codewords with the period n are then used to design a family of frequency-hop-ping codes. The period distribution has been calculated for the general cyclic codes(see[1]).While little is known about the non-cyclic code’s Period distribution.
