Abstract
Abstract A GPS receiver and a portable communication apparatus with the timing of demodulation of a GPS received signal received from a satellite in the global positioning system being controlled in accordance with the timing of transmission of a CDMA transmission signal to a base station in a predetermined communication system, so that the GPS received signal can be accurately demodulated, thereby preventing radio waves that occur during transmission of the CDMA transmission signal from interfering with the GPS received signal. Thus, the GPS received signal can be demodulated without deterioration of reception quality.
