Evaluating the performance of turbo codes and turbo-coded modulation in a DS-CDMA environment.

Turbo codes have received great attention due to their outstanding performance. Unfortunately, a high performance is associated with large transmission delays, prohibiting an application for speech transmission. Hence, the aim of this paper is the comparison of turbo codes employing short interleave...
