マルチパス環境下におけるブロック長制御に基づいたアフィン射影型ブラインドマルチユーザ検出器

抄録

This paper proposes an affine projection type blind multiuser detection with block length control for the improvement of the convergence speed, for DS-CDMA system under the multipath environment. The traditional method to control the block length is discussed under the situation in which the desired signal of the system is given. But, due to the difficulty of the direct application of the above method to blind multiuser detection, some suitable improvements are performed in the proposed method. These ones enable the proposed method to have an advantage compared with the traditional detectors.
