摘要

介绍了一种计算无线分组型调制解调器DFE系数的高效方法。该技术特别适合于硬件VLSI的实现。在用简短的序文估计了信道脉冲响应后，利用高斯-塞德尔迭代算法有效地计算了DFE系数。推导了该算法，并给出了在室内多径信道上QPSK和GMSK调制的结果。

Efficient DFE initialization for high speed wireless LAN

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.
