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 30):
A radio communication system comprising:\n a transmitter to modulate a first signal by performing spread spectrum using a first spreading code, the first signal including information for identifying a second spreading code with a code period longer than the first spreading code, modulate a second signal to be transmitted after the first signal by performing spread spectrum using the second spreading code, and sequentially transmit modulated signals; and a receiver comprising 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 demodulation unit performs, on a signal received by the reception unit, a first correlation process using a first code replica corresponding to the first spreading code and a second correlation process using a second code replica corresponding to the second spreading code, detects a time when the transmitter has switched from the first spreading code to the second spreading code on a basis of a first correlation value obtained by the first correlation process and a second correlation value obtained by the second correlation process, and switches from the first spreading code to the second spreading code at a time corresponding to the detected time, the receiver sequentially receiving signals modulated by the transmitter from the transmitter, by the reception unit.
