For the decode-and-forward (DF) strategy, smart relaying has been shown to achieve the maximal spatial diversity order over Rayleigh fading channels even when erroneous detection is committed at the relays. Due to the importance of Nakagami and Hoyt statistical models in describing channel fading in land, mobile and satellite communications, this paper performs diversity analysis of the smart relaying systems under Nakagami and Hoyt generalized fading channels. Performance analysis proves that, at high signal-to-noise ratio (SNR), the maximal diversity order of the smart relaying system under the Nakagami channel is mSD + min{mSR, mRD}, where mSR, mRD and mSD are the fading figures of the source-relay (S-R), relay-destination (R-D) and source-destination (S-D) links. Under the Hoyt fading channel, the diversity order is 2.
