Abstract :
Adaptive modulation exploits the time-variant channel capacity fluctuation of fading channels using a range of different modem modes according to the equation of the transmission scheme and the results presented in the table. This is achieved at the cost of some latency penalty, which is quantified and mitigated by frequency hopping
