Abstract: An interference canceling method and apparatus reduces the level of signal impinging on a wireless receiver due to the transmitted signal from the same transceiver. A signal sampler, such as directional coupler samples a portion of the transmitted signal. The gain and phase of the sampled signal are adjusted to create an equi-amplitude signal that is 180 degrees out of phase with the unwanted coupled transmit signal. The combination of the gain-phase adjusted signal with the received signal effectively cancels the unwanted transmit signal. Once configured, the interference canceller can continue to operate without further adjustment. Adjustments can be made periodically, however, when necessary to accommodate for changes such as environmental changes.
