Abstract

We obtain upper bounds on the bit-error rate (BER) for turbo-coded optical code-division multiple-access (CDMA) systems using pulse position modulation (PPM.) We use transfer function bounding techniques to obtain these bounds, so our results correspond to the average bound over all interleavers of a given length. We consider parallel concatenated coding (PCC) schemes that use recursive convolutional codes as constituent codes. We consider systems using an avalanche photodiode (APD), and treat APD noise, thermal noise, and multi-user interference using a Gaussian approximation. We compare the performance of turbo-coded systems with that of BCH-coded systems with soft-decision decoding. We show that turbo-coded systems have better performance than BCH-coded systems.
