<p><P>PROBLEM TO BE SOLVED: To provide a communication device which removes external noise stably from a transmission signal produced by modulating a spread spectrum signal, to provide a noise removal method, and to provide a program. <P>SOLUTION: A communication device including: a communication antenna for receiving a transmission signal produced by modulating a spread spectrum signal; an intermediate frequency conversion section for converting a transmission signal received by the communication antenna into an intermediate frequency signal of a predetermined frequency; an analog/digital conversion section for discretizing the intermediate frequency signal and outputting a discretized signal; a noise removing section for detecting noise other than steady thermal noise included in the discretized signal and removing the detected noise from the discretized signal; and a demodulation section for demodulating a spread spectrum signal on the basis of the discretized signal output from the noise removing section. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
