An Alamouti‐type orthogonal space–time‐block‐code transmission over a relay‐based cooperative‐diversity system under the influence of the cooperating nodes’ mobility is considered. It is shown that the high nodes' mobility destroys the optimality of the conventional Alamouit's decoder (ALD) employed at the system's destination, which causes severely degraded error performance. A zero‐forcing‐space–time‐decoder is proposed, to be applied instead of the ALD, and its capability of mitigating this severe impact of the nodes' mobility is shown.
