• MMSE-DFE
• fractionally-spaced
• QR decomposition
• Householder transformation

We present a new parallel algorithm for computing the optimum coefficients of the fractionally-spaced FIR MMSE-DFE based on the Householder orthogonal transformation which avoids the back-substitution computational bottleneck in [1]. The resulting significant reductions in the algorithm's execution time are demonstrated through a real-time FPGA implementation.
