Closed-form bounds for the end-to-end perform-ance of multihop communications with non-regenerative relays over Nakagami-m fading channels are investigated. Upper and lower bounds of the end-to-end signal-to-noise ratio (SNR) are first developed by using the monotonicity. Then, the probability density functions (PDFs), the cumulative distribution functions, and the moment-generating functions (MGFs) of the bounds are derived. Using these results, the bounds for the outage and average bit error probability (ABEP) are obtained. Numerical and simulation results are executed to validate the tightness of the proposed bounds.
