摘要:
A spread-spectrum-signal reception apparatus includes a controller to obtain a phase comparison value that is a phase of a spread code at a time at which initialization of a phase of the spread code is performed and which corresponds to a timing of a top of a frame of a received signal, and to output an initialization instruction including the phase comparison value when having determined that a current time is within a range of a time window; and a signal processor to demodulate the received signal in accordance with the spread code, to perform a frame synchronizing process on the demodulated signal to detect a frame timing, and to perform the initialization at a timing determined in accordance with a result of comparison between the phase comparison value included in the initialization instruction and a phase of the spread code at the frame timing.
