Abstract :
This paper deals with design and studies on the performance of a CDMA scheme with forward error correction coding. A low-complexity non-coherent demodulator is used at the receiver. Convolutional codes with rate 1/2 and variable constraint lengths are considered in evaluating the system performance. Some important conclusions are made based on our studies
