The theory of compressed sensing (CS) considers RIP (Restricted Isometry Property) condition as the sufficient condition of measurement matrix for recovery of any sparse signal from its compressed measurements. The RIP property also preserves enough information for classification of sparse symbols, even ...

The standard deviation of the centre frequency of a signal isinvestigated for the quadrature demodulation technique (QDT). Signalfrequencies can be measure... JW Czarske - 《Measurement Science & Technology》 被引量: 73发表: 2001年 Optimum Demodulation in Pulse Communication Systems Employing Secondar...
The receiver accomplishes LO carrier recovery and data demodulation directly from the RF received signal without resort to resonator based reference, such as crystal oscillator. Integrating LNA, mixer, LO carrier recovery loop, postamplifler, and digital demodulator on a single chip, the total power...
We know that modulation can be defined as the process of changing the carrier signal’s parameters by the instant values of the message signal. The transmission of message signal can be done mainly for communication & the high-frequency signal like a carrier signal doesn’t include data, howeve...
Then, a signal synthesis circuit 17 synthesizes the signals of the respective groups. Thus, the number of points of IFFT can be reduced, the speed of the signal itself is reduced, and the margin of circuit design can be taken to be large. 展开 ...
This paper presents automatic recognition technique of analog modulation scheme and signal waveform detection of the signals in a surveillance system. This system consists of array antenna signal processor and automatic signal recognition/demodulation modules. Firstly, directions of arrival (DOA) of the ...
