An Efficient Circulant MIMO Equalizer for CDMA Downlink: Algorithm and VLSI Architecture
(Hindawi Publishing Corporation, 2006-02-01)
We present an efficient circulant approximation-based MIMO equalizer architecture for the CDMA downlink. This reduces the direct matrix inverse (DMI) of size (NF×NF) with O((NF)3) complexity to some FFT operations with ...
Structured Parallel Architecture for Displacement MIMO Kalman Equalizer in CDMA Systems
A reduced complexity MIMO Kalman equalizer architecture is proposed in this brief by jointly considering the displacement structure and the block-Toeplitz structure. Numerical matrix–matrix multiplications with O(F3) ...
