FFT-Accelerated Iterative MIMO Chip Equalizer Architecture For CDMA Downlink
In this paper, we present a novel FFT-accelerated iterative Linear MMSE chip equalizer in the MIMO CDMA downlink receiver. The reversed form time-domain matrix multiplication in the Conjugate Gradient iteration is accelerated ...
Hermitian Optimization and Scalable VLSI Architecture for Circulant Approximated MIMO Equalizer in CDMA Downlink
In this paper, we propose a parallel and pipelined VLSI architecture for a circulant approximated equalizer for the MIMOCDMA systems. The FFT-based tap solver reduces the Direct-Matrix-Inverse of the size (NF x NF) to the ...
