Abstract:

Multi-dimension lattice constellations are accepted as meaningful means for transmission with high spectral efficiency. Upper bound of symbol error rate of multi-dimension lattice constellation in phase noise channel is derived from pairwise error probability, and the phase noise is constructed as Wiener model. The proposed upper bound can be used to analyze the sensitivity of phase noise in multi-dimension lattice constellation. Simulation results show that with the same normalized spectral efficiency, higher dimension lattice constellations are more sensitive than lower ones in phase noise channel; and with the same dimension of constellation, larger normalized spectral efficiency means more performance loss in phase noise channel.
