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.
