Abstract
A communication terminal device comprising: a plurality of demodulation circuits that correspond to the received signals of the same frequency band, said signals being modulated in the respectively different modulation modes, a decision circuit for determining the modulation mode of each of the received signals whose reception level is greater than a predetermined level, on the basis of the frequency component of the received signal, and a control circuit, which puts one of the demodulation circuits that corresponds to the modulation mode of said received signal to an active state on the basis of the decision made by said decision circuit, and simultaneously puts said decision circuit to an inactive state. Due to this construction, by use of this communication terminal device capable of communicating, in various communication modes corresponding to a plurality of communication system, the total power consumption can be greatly reduced.
