Abstract
An on-vehicle communication device according to the present invention includes initial signal estimating unitfor estimating initial data based on a part of the transmission command signal from the mobile device. Thus, it also includes PN signal generating unitfor generating a PN signal based on the initial data estimated by the initial signal estimating unit, and partial correlating unitfor calculating a correlation value between the transmission command signal from the mobile device and the PN signal. Thus, it also includes a data demodulating unitfor demodulating the transmission command signal from the mobile device, the starting of the data demodulating unit being controlled based on the correlation value calculated by the partial correlating unit
