Title:
ネットワーク・ユーザー識別子を用いる初期化を伴う反復射影
Document Type and Number:
Japanese Patent JP4447777
Kind Code:
B2
Abstract:
A procedure for the semi-blind separation and detection of digital co-channel signals, whereby after a simultaneous spatial-temporal equalization, iterative projections of the symbol vectors to be detected, in a vector subspace or a symbol alphabet Omega of finite size are initialized making use of a network user identifier IDi. These projections are then used to adapt the symbol vectors Si to the vector subspace and to the symbol alphabet Omega of finite size, making use of the method of least squares algorithm but performing only matrix multiplications without eigenvalue or singular decompositions.
