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 results show that the introduction of Turbo code can get the encoding gain of 4.0–6.9 dB, which improves the error performance of system effectively and has advantage in military communications.
