Matched-filter design to improve self-interference cancellation in full-duplex communication systems

A new method for capacity and spectral efficiency increases is a full-duplex communication, where sending receiving are done simultaneously. Hence, severe interference leaked from the transmitter to receiver, which can disrupt system’s operation completely. For reduction, transceiver tries estimate interfering symbols remove their effects. typical use Hammerstein model. In this method, nonlinear power amplifier (PA) multipath channel modeled with successive system finite impulse response filter. Then, model parameters adjusted, estimated transmitted symbols. directly But practically, first pass through pulse-shaping filter become signal. signal passes PA communication channel. Finally, received filtered by matched (MF) at receiver converted again. procedure, affect distort indirectly. Therefore, in practical situation, when we consider transmitter’s receiver’s MF, erroneous. To solve problem, MF proposed adjusted according We have shown that far better than method.
