Modulation classificationFrequency shift keyingBispectrumThis study utilizes higher order spectrum in order to achieve satisfactory probability of correct classification of M-ary Frequency Shift Keying (MFSK) modulated signals even at low signal to noise ratios. MFSK modulated signals are characterized by a...

Multiple hops/symbol FFH-SSMA with MFSK modulation and Reed-Solomon coding for indoor radio 来自 Semantic Scholar 喜欢 0 阅读量: 6 作者:J Wang,M Moeneclaey 摘要: A multiple-hopes-per-symbol fast-frequency-hopped spread-spectrum multiple-access (FFH-SSMA) system for indoor radio communication ...
(2) ForMFSKsignals with different modulation order, the frequency and phase differences of different signals are obvious; (3) Bi-spectrum slice can visually reflects the difference of severalMFSKsignals. 3 that differentMFSKsignals have different bi-spectrum slice curves. ...
A frequency-hopped multilevel frequency shift keying (FSK) modulation technique is employed in a mobile radio communication system, and its bit error probabilities are used with the number of users and repetitions as a performance measure. Bit error probabilities are calculated under the assumption th...
Modulation MFSK ACF — Emission Designator — Bandwidth 154 Hz,218 Hz,316 Hz,330 Hz,435 Hz,630 Hz Location Worldwide Short Description MFSK is a family of multi-frequency shift keying digital transmission modes. MFSK-8 and MFSK-16 are two well-known amateur radio modes. I/Q Raw Recording...
TFSK-MFSK modulation improves the situation that MFSK increases M resulting in low degree of utilization ratio of bandwidth so that it has more frequency combination ways which use the idea of frequency hopping and spread spectrum for reference to signal transmission. And it is not limited at ...
