<P>PROBLEM TO BE SOLVED: To demodulate a received signal normally by improving the power ratio of the received signal to a local station wraparound signal. <P>SOLUTION: A radio communication device includes a spreading unit which spectrum-spreads a transmitted signal based on a spreading code, a wraparound compensating circuit which generates a compensation signal from a part of the spectrum-spread transmitted signal and removes the local station wraparound signal reflected by an antenna for the transmitted signal based on the compensation signal, and a despreading unit which spectrum-despreads the received signal having the wraparound signal removed based on a spreading code different from the spreading code of the transmitted signal and used by a communication partner for spectrum spreading. <P>COPYRIGHT: (C)2010,JPO&INPIT |
