The intersymbol interference caused by dispersion, chirp, and a vestigial sideband filter in intensity
modulation and a direct detection single carrier system is analyzed theoretically and numerically. An iterative
nonlinear intersymbol interference cancellation technique is proposed and experimentally demonstrated in a 40-
Gbps 16-QAM Mach-Zehnder modulator-based vestigial sideband intensity modulation and direct detection halfcycle
Nyquist–subcarrier modulation system over a 100-km uncompensated standard single-mode fiber transmission
for the first time. The experimental results show that 2.2-dB receiver sensitivity improvement is obtained
at the forward error correction limit by using the iterative technique.
