Noise-Robust Modulation Identification Method for Adaptive Receiver Based on Software Defined Radio

In this paper, we propose an effective noise- robust modulation identification algorithm for adaptive receiver based on software defined radio. The proposed method can estimate the carrier frequency, symbol rate, and modulation scheme of the received signal without the use of the handshaking process requiring supplementary information such as the training sequence. Experimental results show that the proposed algorithm demodulates the signal with a low probability of error at the noisy channel conditions.
