A convolutionally coded CDMA data network wherein each user may transmit at one out of a set of possible data rates is considered in this chapter. The problem of joint detection of the data-rate of each user and of the corresponding information symbols is considered. In particular, it is shown here that the so-called turbo principle can be used also for joint rate and data detection, and indeed an iterative (turbo) procedure is derived wherein the single-user decoders, and the datarate detectors for each user exchange information in order to achieve lower and lower detection error probabilities. Numerical results show that the proposed approach is effective and achieves satisfactory performance.
