- 論文の詳細を見る
In this paper, modulation parameters in multiple access systems are discussed to develop new modulations which can be optimized for user-dependent channel. The general orthogonal modulations are used as modulations to be optimized. The general orthogonal modulations are based on orthogonal vectors, which are obtained by multidimensional rotations and have parameters of rotation planes and rotation angles. Each user's transfer matrix of the proposed system is expressed by a Kronecker product of a transfer matrix and a code vector which maintain orthogonality among different users. We find parameters which maximize minimum squared distance for intersymbol interference (ISI).
