He has authored over 500 technical publications, including 200 journal papers as well as four books, entitled Automatic Modulation Classification: Principles, Algorithms and Applications (Wiley, 2015), Integrative Cluster Analysis in Bioinformatics (Wiley, 2015), Blind Estimation Using Higher-Order Statistics (Springer, 1999), and Automatic . Results are presented which show that when the noise process is time-correlated non-Gaussian, the proposed classifier outperforms maximum-likelihood classifiers developed under the assumption that the noise process is either white non-Gaussian or white Gaussian. The asymptotic likelihood function of the estimated feature vector is analytically derived and used with the LRT. By using multiple sampling locations on signal cumulative distributions, the classifier's robustness is enhanced for possible signal statistical variance or signal model mismatching.

Other than small experiments and a few highly specialized military systems, the theory had little interaction with practice. Existing modulation classification algorithms can be divided into 2 main classes: 1) Probabilistic based algorithms (likelihood-based algorithms); 2) Feature-based algorithms. Experimental results show that the proposed AMC scheme achieves higher classification accuracy in both slow and fast fading channels when compared with the traditional deep learning based AMC schemes. Cognitive radios have become a key research area in communications over the past few years.

Automatic modulation classification (AMC) is a critical algorithm for the identification of modulation types so as to enable more accurate demodulation in the non-cooperative scenarios. use a 35-speaker free-response speech database of subjects treated for depression over a 6-week duration. Our approach provides a general framework for analyzing individual symptom categories through phonological units, and supports the premise that speaking rate can be an indicator of psychomotor retardation severity. Using only 200 128-point samples per modulation scheme (1% of the available signal samples) and a proper selection of a classification algorithm, DASAR reaches accuracy up to 70.96% compared with a maximum accuracy of 43.62% using the state-of-art methods tested under the same conditions.

Survey of automatic modulation classification techniques: classical approaches and new trends. 378-382 Google Scholar Compared to previous works, the proposed characterization (frequency band status and direction-of-arrival estimation) approach does not need prior knowledge of received signal distribution. This is a time-consuming manual process that slows down a security analysis. $95.50 (hardcover), ISBN: 0471741094. The estimation is achieved by minimizing a signal-to-centroid distance. In classification of signal modulation types in MIMO systems, it is difficult to achieve both high accuracy and high computational efficiency at the same time. The performance of this dual-determination scheme shows high modulation recognition accuracy and low mean SNR estimation error. The Cramér–Rao lower bound (CRLB) and modified Cramér–Rao lower bound (MCRLB) for MIMO SNR and MIMO noise variance estimation are determined for digital constellations such as BPSK, QPSK, 8PSK, and 16QAM. Furthermore, the overhead of online retraining under time-varying fading channels has not been studied in the prior arts. Automatic modulation recognition is advantageous for wireless communication systems employing adaptive modulation, software-defined radio, and cognitive radio. Nowadays, it is of great importance, especially in the military and commercial industries, to classify such signals which have unknown modulation type quickly and automatically with minimal error, ... Table 2 compares the proposed method with [32] for BPSK, QPSK, and 16QAM modulation schemes. SDRs, however, deliver raw signals that have to be demodulated and decoded before researchers can reverse-engineer the protocol format. The influence of this Thomas Bayes' work was immense. Blind modulation classification is a very difficult task without information about the transmitted signal and the receiver parameters like carrier frequency, signal power, timing information, phase offset, existence of frequency‐selective multipath fading, and time‐varying channels in real‐world applications. When different channel conditions are simulated, the proposed blind classifier achieves similar classification accuracy versus non-blind state-of-the-art classifiers while being more robust and having much lower complexity.
