Abstract

In the design of software defined radio (SDR) and cognitive radio (CR), new and flexible digital baseband algorithms are required for generating and decoding a variety of waveforms. Especially, blind identification of the waveform parameters, modulation types, and synchronization parameters are extremely important. In this article, we propose a modulation identification algorithm in which no a priori information is assumed about the constellation map. The proposed algorithm can identify the modulation, even if short data record is available. Moreover, numerical results are provided to show the performance of the proposed approach under certain assumptions.
