Piece-Wise Linear Multi-Channel Complex Microstatistic Filters

In this contribution, the structure and design procedure of a new time-invariant complex multi-channel conventional microstatistic filter (C-M-CMF) will be proposed. The C-M-CMFs belong to a group of minimum mean-square estimators based on the estimation of a desired signal by using a linear combination of vector elements obtained by a suitable decomposition of the input signals of the filter. The C-M-CMF represents a modification of multi-channel conventional microstatistic filter (M-CMF) originally developed in [1-3] as a part of microstatistic multi-user receiver of CDMA transmission systems for real signal processing. It is expected that the C-M-CDMA theory developed in this paper can be applied for the design of a new complex receivers for MC-CDMA transmission systems.
