SYMBOL RATE ESTIMATION DEVICE AND SYMBOL RATE ESTIMATION METHOD

摘要

A symbol rate estimation device includes: a power spectrum density (PSD) generating unit, estimating a power of an input signal to generate a PSD; a cut-off frequency index outputting unit, outputting a cut-off frequency index according to the power; and a symbol rate calculating unit, calculating a symbol rate of the input signal according to the cut-off frequency index.
