Modulation detection is one of the major tasks of an intelligent receiver in a software defined radio (SDR). It is an intermediate step between signal detection and demodulation. In this paper we present the modulation detection based on Dynamic Time Warping (DTW) algorithm. Here the types of modulation that we use are QPSK, 8-PSK, 16-QAM and 64-QAM. The whole test and verification has been done with the help of SDR platform. After the test and trials of all the modulation schemes, it is observed that DTW provides a good efficiency with the accuracy of 93.75%.
