Abstract:

A simple amplify-and-forward (AF) relaying scheme based on Orthogonal Space-Time-Codes (OSTBC) is proposed, which applies to the scenario where only one single antenna at the relay and an arbitrary number of antennas at the destination. Also, the analytical performance of the proposed scheme is investigated in the context of Rayleigh fading channels. Specifically, the probability density function (pdf) of the received SNR is characterized and the symbol error rate (SER) of different modulation schemes is derived. Simulation confirms the validity of analytic results.
