Analysis of error performance for Turbo coded pulse position width modulation

Abstract:

To lower the bit error rate (BER) of the pulse position width modulation (PPM+PWM),which is the improved scheme of the pulse position modulation (PPM),correcting coding technique is necessary. 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. The res...
