Abstract
Rising development in software Defined Radio(SDR) systems has led to rapid development in Blind Modulation Detection (BMD) techniques. Different order modulations combined with different coding schemes allow sending more bits per symbol, thus achieving higher throughputs and better spectral efficiencies by the use of BMD. A generalized Digital Modulation Identification algorithm for adaptive demodulator has been implemented. The algorithm is verified using Wavelet Transform and histogram computation to identify BPSK QPSK, M-ary PSK, 16-QAM and GMSK signals. The proposed method is implemented using MATLAB Simulink tool and the simulations are also carried out in the same.
