Adaptive equalization techniques for moderately fading mountainous terrain scenarios

摘要

In mountainous propagation scenarios for digital mobile radio communications with moderate fading and with rapidly changing channel characteristics adaptive equalization concepts must be applied to achieve a sufficient low bit error rate in the demodulator. It is shown that the decision feedback equalizer (DFE) with its coefficients derived from the estimation of the channel impulse response yields a better performance with less implementation complexity than the recursive least squares (RLS) lattice equalizer which directly adapts its coefficients.
