After setting up the analytic model,the Turbo decoder and iterative algorithm for PPM+PWM are studied,and the system error performance of uncoded and Turbo coded PPM+PWM under the Gaussian channel is simulated and analyzed,as well as the effects of the number of iterations and frame size on the bit error rate.
