In wireless relay networks, transmission delays among relay nodes will lead to substantial performance degradation, for which distributed linear convolutive space-time codes (DLC-STCs) are proposed. This paper analyzes the diversity order of the DLC-STCs on fast fading Rayleigh channels. It is shown that the DLC-STCs can achieve full asynchronous cooperative diversity order with maximum likelihood (ML) receivers on fast fading Rayleigh channels, although it is originally proposed for slow fading channels. The numerical results verify the theoretical analysis and show that MMSE-DFE receivers, can collect the same diversity order as ML receivers on fast fading Rayleigh channels.
