Abstract

Additive noise Blind equalizers Deconvolution Delay effects Finite impulse response filter MIMO Multiaccess communication Noise measurement Signal processing algorithms Vectors
Tugnait's multi-input multi-output inverse filter criteria (MIMO-IFC) using either second- and third-order or second- and fourth-order cumulants for blind deconvolution are extended to those using second- and higher-order (≥ 3) cumulants. Next, a blind maximum ratio combining (BMRC) method using the MIMO-IFC is proposed. Then a blind equalization algorithm for multiuser DS/CDMA systems in multipath channels is proposed using the proposed BMRC method and MIMO-IFC. Finally, some simulation results are provided to support the proposed algorithm. © 2001 IEEE.
