Adaptive thu phát không dây P1
In recent years the concept of intelligent multi-mode, multimedia transceivers (IMMT) has emerged in the context of wireless systems [l-61. The range of various existing solutions that have found favour in already operational standard systems was summarised in the excellent overview by Nanda et al. [3]. The aim of these adaptive transceivers is to provide mobile users with the best possible compromise amongst a number of contradicting design factors, such as the power consumption of the hand-held portable station (PS), robustness against transmission errors, spectral eficiency, teletrafic capacity, audiohideo quality and so forth [2]....
