Abstract
A signal receiving apparatus includes a phase recovery look, a phase estimation circuit, a phase noise detection circuit, and a bandwidth setting circuit. The phase recovery loop performs a phase recovery process on an input signal according to a bandwidth setting. The phase estimation circuit generates an estimated phase associated with the input signal. The phase noise detection circuit determines a phase noise amount according to the estimated phase. The bandwidth setting circuit calculates an average and a variance of the phase noise amounts, and adjusts the bandwidth setting of the phase recovery loop according to the average and the variance.
