QAM implementation in the radio systems: a survey
Gustaw Mazurek · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2006
This paper summarizes our recent literature research focused on M-QAM implementation in the radio channel. Reviewed papers include analytical studies, as well as the results of computer simulations and experiments on practical working systems. Current DSP techniques of channel estimation, equalization and adaptive modulation are presented. Our research in adaptive QAM DS-CDMA system is also described.
