WIRELESS MODEM FOR CANCELLING NOISES AND A METHOD FOR CANCELLING NOISES USING THE SAME, PARTICULARLY FOR IMPROVING AN SNR(SIGNAL TO NOISE RATIO)

摘要

PURPOSE: A wireless modem for cancelling noises and a method for cancelling noises using the same are provided to efficiently remove noises through a noise signal removal of a wireless modem when the noises of a device having a wireless modem is maintained in an antenna of the wireless modem.;CONSTITUTION: A main antenna unit(110) receives a wireless signal including noise signal transferred from a device connected to a wireless modem, and a sub antenna unit(120) receives the noise signal. A noise signal adjustment unit(154) adjusts the noise signal of the sub antenna unit based on the correlation parameters between the noise signals of the main and sub antenna units. A noise signal remover(152) removes the adjusted noise signal from the wireless signal.;COPYRIGHT KIPO 2011
