Abstract
The main problem investigated in this research is the recovery of signals measured by inaccurate sensors, which normally has a tendency of distorting signal information, both in the time domain and frequency domain. A scheme for signal recovery by Jayasuriya and Langari is investigated. Some simulations are made to check its range of application and see if it is possible to improve the method for wider practical application. Through the investigation, we found that this method has application limitation since it could not handle the case where the conditions go a little beyond the sufficient conditions of the theorem. We also found that it has a drawback in practical application in that it requires the exact sensor function, which is mostly not possible in practice. Since this drawback could not be overcome through a revision of the original scheme, a new signal recovery method based on energy modulation is developed. Simulations show that it gives a good direction to find a practical signal recovery method with a wider application range since it does not require a priori knowledge of the sensor function.
