Abstract
The multicarrier OFDM technology has been chosen by many recent networking standards as preferred modulation scheme at physical layer as it offers high robustness against multipath effects. Automatic modulation recognition of OFDM signal has been thus intensive research area in cognitive radios. Several algorithms have been proposed in past that carry out effective detection, parameter estimations, and automatic recognition of OFDM signals as part of radio sensing techniques. In this paper, we proposed neural network-based classification of WiMAX IEEE 802.19 physical layer OFDM signal which does not require any a priori information or depends on cooperative embedded information from transmitter. The proposed algorithm classifies WiMAX IEEE 802.16d OFDM signal in a heterogeneous network environment having other digital modulation signals. The proposed features are robust to channel noise and multipath fading effects on wireless channel.
