The channel estimators studied namely Zero Forcing (ZF), Minimum Mean Square Error (MMSE)...
Active analogue self-interference cancellation (AASIC) techniques are used to prevent the saturation of the receiver chain in full-duplex (FD) radios. This is done by cancelling the self-interference (SI) signal before it enters the receiver chain. AASIC techniques are usually implemented...
