TLDR
A modular parallel architecture for a MMSE-DFE coefficient computation processor is presented that is based on the QR factorization of a channel-and-noise-dependent data matrix and is implemented using CORDIC processors within a systolic array architecture.Abstract:
A modular parallel architecture for a MMSE-DFE coefficient computation processor is presented. The architecture is based on the QR factorization of a channel-and-noise-dependent data matrix and is implemented using CORDIC processors within a systolic array architecture. Implementation issues including the number of CORDIC stages and the bit precision required in a fixed-point implementation are investigated through computer simulations.read more

DFE-Based Receiver Implementation for MIMO Systems Employing Hybrid ARQ
TL;DR: It is shown how the theory of MIMO decision feedback equalization can be applied to derive optimal DFE architectures for the case of M IMO HARQ, and incremental structures are proposed that reduce the implementation complexity of the DFE and the memory requirements at the receiver without loss in performance.
