In this article, the structure and design procedure of a new time-invariant complex-valued multi-channel non-linear 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 desired signals by using a linear combination of vector elements obtained by a threshold decomposition of the input signals of the filter. The C-M-CMF represents a modification of multi-channel real-valued conventional microstatistic filter (M-CMF) originally developed in [4, 10, 11] for the purpose of design of a non-linear multi-user receiver for code division multiple access transmission systems (CDMA). The C-M-CMF theory developed in this paper can be applied for the design of new complex-valued receivers for multi-carrier code division multiple access transmission systems (MC-CDMA).
