N2 - In this letter, a new detector is proposed for amplifyand-
forward (AF) relaying system when communicating with the
assistance of relays. The major goal of this detector is to improve
the bit error rate (BER) performance of the receiver. The probability
density function is estimated with the help of kernel density
technique. A generalized Gaussian kernel is proposed. This new
kernel provides more flexibility and encompasses Gaussian and
uniform kernels as special cases. The optimal window width of the
kernel is calculated. Simulations results show that a gain of more
than 1 dB can be achieved in terms of BER performance as compared
to the minimum mean square error (MMSE) receiver when
communicating over Rayleigh fading channels.
