摘要：
In this paper, the performance of distributed space-time block coded (DSTBC) orthogonal frequency-division multiplexing (OFDM) system (DSTBC-OFDM) with the presence of carrier frequency offsets is investigated. Since the transmit antennas belong to different nodes that are distributed, there may exist multiple carrier frequency offsets to the transmitters at the receiver of DSTBC-OFDM system. The system model of DSTBC-OFDM with multiple carrier frequency offsets is given. Then we propose a frequency-domain detector to cancel the inter-symbol interference and the inter-carrier interference when detecting the symbols. The proposed detector has a reasonable performance and a moderate computational complexity. Simulation results show that the detector works very well when the carrier frequency difference between the distributed transmitters is small.
