Note. is the remainder between a and b. is the largest integer less than or equal to . and are the number of encoding phase, but the difference is that has to take the ability that can open square values. and are the iterative integer values from 1 to . is the number of phase state. is the number of step frequencies. is the fixed carrier frequency value. , , and , respectively, represent different frequency jump sequences of corresponding signals, where , , and . is the pulse width. and are constants.
