FREQUENCY HOPPING SPREAD SPECTRUM COMMUNICATION EQUIPMENT, METHOD FOR CONTROLLING FREQUENCY DEVIATION OF THE SAME, AND METHOD FOR OBTAINING COEFFICIENTS TO BE USED FOR CONTROLLING THE FREQUENCY DEVIATION

摘要

PROBLEM TO BE SOLVED: To provide GFSK radio equipment which keeps a frequency deviation within a prescribed range in a simple configuration regardless of the RF frequencies.;SOLUTION: The voltage amplitude of a modulating signal which is outputted from a GF 116 is controlled by using coefficients stored in an external storage device 170. The coefficients are collectively obtained by linear interpolation using the result of frequency deviation measurement which is previously performed about two RF frequencies. The GF 116 includes a multiplier for controlling the voltage amplitude of the modulating signal by multiplying transmission data by the coefficients.;COPYRIGHT: (C)2003,JPO
