An investigation on mixing real-time and non-real-time services in UTRA is presented. The main objective of this work is to observe and understand how service characteristics of bit-rate, mean connection duration, required E/sub b//I/sub 0/ and delay tolerance, influence the performance of radio resource management (RRM) in supporting mixed real-time and non-real-time services.

This correspondence presents sequential algorithms for soft decision decoding of linear block codes. They use a stack algorithm based on the trellis of the code. We are interested in the trellis as a means to avoid path-decoding repetitions. As well, the possibility of bidirectional decoding offers a chance to increase the likelihood of explored paths. We have developed three successive algorithms that offer a good decrement in the overall complexity, and mainly in the most complex decoding case, while giving near-maximum-likelihood performance. This is important since it determines the maximum buffer size necessary in the decoder.
