Construction of algorithm for frequency hopping code generator using counting TOD
计数式TOD跳频码发生器算法的构造

It is necessary to use the reference real time TOD(Time Of Date) for synchronizing a hopping sequence with long period. There is a new view that the generation of hopping codes is a process in which the special information sequences TOD are translated by a block encoding. Today monotonously increasing TOD is a common form, but there are collides between existing generating algorithm of hopping code and monotonously increasing TOD with long period. A important task of study on generating algorithm of hopping code which is suitable for monotonously increasing TOD with long period and keeps good properties is discussed in the paper.
