This paper focuses on the classification of the MPSK modulations using compressive measurements in additional Gaussian white noise (AWGN). Under the compressive sensing (CS) frame, the compressive maximum-likelihood (CML) classifier provided in this paper tries to recognize the MPSK signals using far fewer samplings than traditional maximum-likelihood (TML) classifier needs. This paper presents the criterion of classification and the classification performance analysis. Finally, several numerical simulations are provided and the results indicate that the CML classifier have a satisfied performance in higher SNR with far lower complexity. It's an effective approach to promote the real-time property of communication system.

In this article, a newly-developed flowmeter for coal injecting, model MLJ-3, is discribed. It consists of a sensor and a microprocessor-based transmitter with indicating and total device. This type of flow-meter works on the principle of capacity-noise and a special function to compensate the variation of electrical properties of coal automatically. Its accuracy is better than 5percent F.S.. The compensating method is also stated in this article.
