PURPOSE:To demodulate a pure SSB modulation signal by taking correlation to an SSB input signal and an SSB re-modulated signal at a complex correlation device and using the correlation value to control a complex multiplier to demodulate the SSB-PSK modulation signal while its frequency and phase ...
For example, when we looking at an object illuminated by Sun, we percept the visual signal resulting from modulation of the sunlight (carrier) by the spatio-temporal distribution of the light-reflection coefficient of the object (modulating signal). Our visual information mainly is provided by ...
Multiple peaks of autocorrelation function of binary offset carrier(BOC)modulated signal can lead to ambiguity of signal acquisition.To solve the problem,a correlation multiplication side-peak cancellation technique(CMSCT)is proposed.Based on the special property of sub-correlation function of BOC signal...
Finally many simulations have been conducted and it is shown that, our method is capable to classify the right modulation against an SNR (Signal to Noise Ratio) of less than 5 dB. The classification rate is 100% for PSK and ASK signals, and 96.5% for OFDM signals. No explicit prior ...
In an AM radio signal receiver, the value of Q of the input tuning circuit is varied in accordance with information indicative of the magnitude of the received signal. This information may be derived from the intermediate frequency (IF) signal processing stage of a superheterodyne receiver. In ...
In this paper,the Discrete Fourier Transform of PSK modulated signal'instantaneous amplitude is calculated,and the corresponding frequency value of discrete spectrum line after transform is detected to estimate the symbol rate.The principle and the per- formance of this method are fetched in detail....
To this end, a receiving signal is preferably converted to an intermediate frequency band ( omega ZF), filtered and A/D converted. The receiving signal is subsequently converted to the baseband and channels are selected in a digital manner by means of a digital complex multiplier (9) before ...
