| Abstract(in English) | Much attention has been paid to millimeter-wave (mmW) radio communication providing large capacity. As well, maintaining its communication quality is one of the crucial issues, and diversity approaches should be effective ways in terms of physical layer. Differential Space-Time Block Coding (DSTBC), which is a spatial diversity strategy, has robustness against phase noise seriously specific to mmW. Although multiple received antennas can improve the quality, employing less received antennas is required to establish reasonable systems. Therefore, exploiting abundant frequency resources of mmW, we develop a strategy of two-dimensional diversity by introducing spectral precoding as outer coding of DSTBC. In this paper, we first clarify a couple of issues appeared in the examined two-dimensional diversity scheme: (i) low-power signals observed after spectral precoding and (ii) imbalance of equivalent noise variances between subcarriers at DSTBC decoder outputs. Then we propose the two solutions noise imbalance at DSTBC decoding, respectively. The performance evaluation using computer simulations reveals that the proposed solutions can yield the performance gain up to 4dB at BER=10E-4. |
