Chord Recognition Based on Temporal Correlation Support Vector Machine

Autor: Zhongyang Rao, Xin Guan, Jianfu Teng

Publikováno v: Applied Sciences, Vol 6, Iss 5, p 157 (2016)

In this paper, we propose a method called temporal correlation support vector machine (TCSVM) for automatic major-minor chord recognition in audio music. We first use robust principal component analysis to separate the singing voice from the music to

Frequency offset estimation in the intermediate frequency for satellite-based AIS signals

Autor: Shexiang Ma, Jianfu Teng, Chen Liu, Xin Meng

Publikováno v: Optoelectronics Letters. 14:301-305

In this paper, an accurate frequency offset estimator is investigated in the intermediate frequency for the satellite-based automatic identification system (AIS) signals. Using Gaussian minimum shift keying (GMSK) modulation for transmission, the AIS

Time Delay Estimation of AIS Signal Based on Three-Order Cumulant

Autor: Dawei Zhao, Shexiang Ma, Jianfu Teng, Xin Meng

Publikováno v: Wireless Communications and Mobile Computing, Vol 2018 (2018)

A time delay estimation algorithm based on three-order cumulant with the different symmetry of modulation signal between training sequence and information sequence of AIS (Automatic Identification System) is presented, which aims to overcome the larg

Frequency Offset Estimation of Satellite-Based AIS Signals Based on Interpolated FFT

Autor: Xin Meng, Chen Liu, Jianfu Teng, Shexiang Ma

Publikováno v: Wireless Personal Communications. 99:35-45

Aimed at addressing the problem of carrier synchronization for satellite-based Automatic Identification System (AIS) signals, a novel data-aided carrier frequency offset estimation method in the intermediate frequency is proposed in this paper. AIS s
