 note = {一般的なマイクロホンアレーでは，厳密に指定可能なヌル方向はマイクロホン数未満に制限される．一方，我々は 2 マイクロホン受音系出力の乗算に基づく手法を提案し，一定のゲインを有する抑圧区間の実現に成功している．この手法は方向制約条件に基づいているが，その制約を外せば任意の指向性の近似問題として扱うことができる．本研究では，メタ戦略による設計法について検討する．, In general system of microphone arrays, the number of nulls is strictly limited under the number of microphones. We have succeeded to realize a suppression section having a constant low gain by using just two microphones. This method is based on some directional constraints. Removing those constraints, a directivity design problem can be formulated as an approximation problem to an ideal directivity characteristic. In this paper, such a problem is solved by meta-strategy method.},
