%X The performance of distributed space-time code can be severely degraded due to timing offsets among relay nodes. Focusing on this problem, an Asynchronous Distributed Linear Convolutional Space-Time Code (ADLC-STC) is proposed in this paper. By designing a family of generating matrices with special structures, the proposed ADLC-STC can achieve full diversity order under frequency-selective channels without the synchronous assumption. Moreover, because of its linearity, the proposed ADLC-STC can be decoded by zero-forcing (ZF), MMSE, MMSE-DFE detectors. Theoretical analysis and simulation results show that, with the suboptimal detectors, the ADLC-STC can achieve full diversity order without the synchronous transmission assumption.
