Antenna cancellation used for collocated radios

An interference cancellation scheme combining Antenna Cancellation, RF Cancellation and Digital Cancellation is presented in this paper. The simulation result present that the mutual interference can be sufficiently cancellated. Instead of past works using software layer approaches to solve the compatibility of Bluetooth and Wi-Fi, great improvements in RF hardware circuit is able to guarantee both wireless networks can work at the same time independently aiming to achieve the high efficiency of signal transmission. This method is extensible to other mutually interfering radio devices.
