Abstract
A method for maintaining good cancelation in a passive feed-forward cancelation circuit is disclosed. The feed-forward cancelation circuit may include at least one path which may comprise a phase-shifter and a variable attenuator. This method uses the complex value of the reflection coefficient at the point where the communication device is connected to a transmission medium, such as an antenna, to determine the values for the phase shifter(s) and the variable attenuator(s).
