Abstract
We propose a novel RF pulse shape and evaluate its performance for QPSK, PM-QPSK and 16 star QAM modulation formats under the effects of phase noise, preamplifier noise, dispersion and nonlinearity. Simulation of a 100 Gbps system with proposed pulse shape shows significant BER reduction compared to the system with rectangular pulse shape.
