Future Wireless - Trends and Challenges
----------------------------------------------------------
In this talk the trends of several wireless communications aspects,
including wireless technology, services, device technology, research
and markets are discussed. Furthermore, an approach in distributed
turbo coding (DTC) with soft information relaying is examined.

Instead of making hard decisions on the transmitted information
symbols, as in the conventional DTC systems, the relay calculates and
forwards the soft estimates of the transmitted symbols in the form of
a posteriori probabilities. The proposed scheme has a significantly
better performance than the conventional DTC. It approaches the
performance of the DTC with automatic repeat request (ARQ) at the
relay, with a much higher throughput. The scheme can be applied in
wireless sensor and ad hoc networks.
