The constrained capacity of the additive white Gaussian noise channel affected by Wiener phase noise is investigated in the letter. Evaluation of channel capacity based on quantization of the phase space and trellis representation of the memory is proposed. The results presented in the letter show that quantization of the phase into 128 bins is adequate to accurately evaluate the capacity at signal-to-noise ratio lower than 30 dB.
