Abstract-- Adaptive modulation is a method to increase the
data capacity, throughput and efficiency of time division du-
plexed wireless communication systems. In adaptive modulation,
the transmitter continually monitors the dynamic channel and
adjusts the transmission parameters such as modulation order,
coding rate etc. accordingly. Blind modulation detection schemes
play an important role in adaptive systems to eliminate the
need for transmitting modulation information, thereby increasing
spectral efficiency. In this paper, an improved statistical blind
modulation detection method based on the Kullback-Leibler
distance is proposed for OFDM based wireless communication
systems. Simulation results show that this blind modulation
detection algorithm outperforms similar previously proposed
algorithms.
