Photoplethysmographic signals are synthesized using a Fourier representation with a fundamental and 2 harmonic components, and an accurate method for parameter estimation using this synthesis model is discussed. The estimated parameters enable to determine physiologically meaningful features related to arterial stiffness, heart rate variability, blood pressure variations, etc. The method allows signal...
A Discrete Fourier transform (DFT) based method for estimating a sequence of frequencies is presented. The method is computationally efficient and also meets the Cramer-Rao bound. The method is then used for symbol detection in a Continuous Phase Modulation receiver. The performance of detection has been analyzed and simulation results are provided for comparison against other existing algorithms...
We present a comparison on direction-of-arrival (DOA) parameter identifiability between multiple-input multiple-output (MIMO) and phased-array radar, which could be considered as additional work to the literature of comparison between these two systems. Conventional and advanced transmission strategies are considered, i.e., transmission without and with beampattern synthesis, respectively. At the...
Novel instantaneous frequency estimation based symbol detection is proposed for implementing Continuous Phase Modulation receivers. The method is simple as only two symbol periods are used. An efficient instantaneous frequency estimation algorithm that could be used in the implementation is also proposed. The performance of the method has been analyzed and simulation results are provided for comparison...
This paper proposes and investigates a discrete Fourier transform based receiver for continuous phase modulation. The architecture is robust and thus can be used even if the channel exhibits Doppler spreading. e.g. due to fading and relative motion as in an wideband underwater communication channel. The proposed receiver performance is compared with other widely used receivers such as the Viterbi...
