| Abstract(in English) | This paper reports laboratory experimental results on a time division multiple access/time division duplex based adaptive modulation system (AMS/TDMA/TDD) to achieve high quality 1-2 Mbit/s data transmission as well as to flexibly support wide variety of quality of services (QoS) for future wireless multi-media communications systems. The developed system employs a symbol rate and modulation level controlled adaptive modulation technique in which modulation scheme is selected from full-rate 64QAM, full-rate 16QAM, full-rate QPSK, 1/2-rate QPSK, 1/4-rate QPSK, 1/8-rate QPSK and no transmission according to the expected channel condition for the transmitted signal. The results show that the performance of the developed AMS/TDMA/TDD system agrees very well with the theoretically expected performance, and the AMS/TDMA/TDD is very effective to achieve high quality high bit rate wireless data communications. |
