ABSTRACT:
PL demodulation section203demodulates pilot signals of a received signal. SIR detection section205detects the reception quality of the demodulated pilot signals. fd detection section206detects a Doppler frequency using the demodulated pilot signals. Requested modulation method deciding section207decides a modulation method to be requested to the base station using the reception quality of pilot signals and the detected Doppler frequency. Command generation section208generates a command corresponding to the decided modulation method. Adaptive demodulation section204performs demodulation processing on the received signal using the demodulation method corresponding to the modulation method decided by requested modulation method deciding section207. This makes it possible to maintain good reception quality even in a fading environment.
