Abstract :
The use of multi-stage successive interference cancellation (M-SIC) for super-Nyquist transmission is proposed. Simulation and transmission experiment results showed carrier spacing was reduced by 20% for QPSK signals. Signal performance was enhanced when M-SIC was used with non-uniform power transmission.
