Abstract |
|
With the advancement of communications technology comes with the demand for higher data rate services such as multimedia, voice, and data over both wired and wireless links. New modulation schemes are required which must be able to adapt to different requirements of individual services in terms of their data rate, allowable Bit Error Rate (BER), and maximum delay. To improve the BER performance, modulation scheme which is used these days is Adaptive Modulation In this paper, we present review adaptive modulation scheme with channel conditions being varied. |
