Abstract
A very efficient procedure is introduced for computing the DFE coefficients for wireless packet type modems. The technique is especially suited for hardware VLSI implementation. After the channel impulse response is estimated using a short preamble, the Gauss-Siedel iterative algorithm is efficiently used to compute the DFE coefficients. The algorithm is derived and results are shown for both for QPSK and for GMSK modulations on indoor multipath channels.
