In this paper, we analyze the performance of a multihop system in which a relay is selected sequentially among multiple non-regenerative relays in each hop. We employ multiple antennas at the destination to remove the bottleneck at the last hop caused by the sequential relay selection proposed. By deriving the moments of an upper-bound on the end-to-end signal-to-noise ratio (SNR) using order statistics, we provide a bound on the average symbol error probability of MPSK which can be applied for arbitrary numbers of relays and hops.
