説明
This paper proposes new weight optimization method of an adaptive array antenna (AAA) for radio relay system in which AAA employing directional antennas is used at base station. Our proposed method improves the conventional method using common pilot sequence and transmission timing offset. The key idea of our method is use of pseudo reference signals which is included non-signal parts which is obtained by the transmission timing offset. It keeps a linear independence of the pilot signals which improves the accuracy of the receive weight optimization. In addition, we carried out channel measurements and our method is evaluated by simulations using the measured delay profiles. Finally, it is shown that our proposed method can improve the performance in actual environment.
