Wireless modem and noise cancellation method for the same

摘要

A wireless modem and noise cancellation method for the same for noise cancellation effectively cancels a noise signal induced from a device to which the wireless modem is connected. A primary antenna receives a radio signal that includes a first noise signal coming from a device to which the wireless modem is connected; a secondary antenna receives a second noise signal from the connected device; a noise signal adjuster for adjusting the second noise signal received by the secondary antenna using a correlation parameter between noise signals received by the primary antenna and the secondary antenna; and a noise remover subtracts the noise signal adjusted by the noise signal adjuster from the radio signal received by the primary antenna.
