N2 - This paper presents a system with auto selection technique to reduce impulsive noise effect in wireless communication systems. The impulsive noise is detected through comparison with a fixed reference. The selection of the appropriate reduction technique to be applied is based on an estimation of the rate of impulsive noise occurrence. The proposed system uses subtraction-gating for low occurrence rate, conventional limiting for high occurrence rate, and passes the incoming signal to the output in the absence of impulsive noise. The results for QAM and FSK through simulation as well as realtime implementation on an FPGA development system are presented and show marked improvement in the bit error rate in each case.
