Abstract:
A receiver includes a reception antenna, a reception unit, and a demodulation unit. The reception unit sequentially receives modulated signals resulting from spread spectrum via the reception antenna. The demodulation unit demodulate a first signal received by the reception unit by performing despreading using a short-period spreading code, the first signal including information for identifying a long-period spreading code. The demodulation unit identifies the long-period spreading code on the basis of the information obtained from the first signal. The demodulation unit then demodulates a second signal received by the reception unit after the first signal by performing despreading using the long-period spreading code.

Claim (Index 27):
A receiver comprising:\n a reception unit to sequentially receive modulated signals resulting from a spread spectrum from a transmitter; and a demodulation unit to demodulate a first signal received by the reception unit by performing despreading using a first spreading code, the first signal including information for identifying a second spreading code with a longer code period than the first spreading code, identify the second spreading code on a basis of information obtained from the first signal, and demodulate a second signal received after the first signal by the reception unit by performing despreading using the second spreading code, wherein the signal received by the reception unit is a signal of frames each including a frame number for identification in a header, the first signal further includes information indicating a frame number corresponding to a time when the transmitter has switched from the first spreading code to the second spreading code, and each time a signal is received by the reception unit, the demodulation unit compares a frame number included in a header of a frame obtained from the received signal with the frame number indicated by the information obtained from the first signal, and switches from the first spreading code to the second spreading code when the frame numbers match with each other.
