Evaluation of Key Techniques for Packet Traffics in Multi-Carrier LCR TDD Systems

This paper researches key techniques and the scheduling strategies in multi-carrier LCR TDD (low chip rate time division duplex) systems. We propose a new PF (proportional fairness) scheduling algorithm based on rate-prediction, and different scheduling strategies combined with SA (smart antenna) or JD (joint detection), which improve the throughput of packet traffics are simulated in dynamic system layer simulation. As some curves are obtained, we can get the dependency relationship between different kinds of technologies.
