Abstract: Determination of the coherence bandwidth for multipath fading channels is of great importance for wireless systems design. However, the calculation of the coherence bandwidth so far has relied on an empirical formula. In this paper, we derive an exact coherence bandwidth formula for Rayleigh fading channels. The use of the new formula is illustrated by numerical results.
