Velocity estimation using recursive ultrasound imaging and spatially encoded signals
Previously we have presented a recursive beamforming algorithm for synthetic transmit aperture focusing. At every emission a beamformed low-resolution image is added to an existing high-resolution one, and the low-resolution image from the previous emission with the current active element is subtracted yielding a new frame at every pulse emission. In this paper the method is extended to blood v...
متن کاملDirection of Arrival Estimation of OFDM Signals Using Cyclostationarity
Direction of arrival estimation has many applications in communications. Though MUSIC and ESPRIT are by far the mostly studied algorithms, there have been growing interests in cyclostationarity based algorithms for their higher selectivity. In addition to carrier frequency and baud rate, OFDM signals show cyclostationarity caused by the cyclic prefix. In this paper we have studied the direction...
متن کاملPosition and velocity estimation through acceleration measurements
This paper proposes a solution to the problem of velocity and position estimation for a class of oscillating systems whose position, velocity and acceleration are zero mean signals. The proposed scheme considers that the dynamic model of the system is unknown and only noisy acceleration measurements are available.
متن کاملMulti-azimuth velocity estimation
It is well known that the inverse problem of estimating interval velocities from reflection data is poorly constrained in 2-D. We show that the interval velocity estimation problem in 3-D is much better constrained when the velocity function is estimated by jointly inverting the data collected along multiple offset-azimuth, even when the azimuth range is fairly limited. We extend to 3-D the lin...
متن کاملFrequency estimation for single-carrier and OFDM signals in communication and radar systems
Estimating the frequency of a signal embedded in additive white Gaussian noise is one of the classical problems in signal processing. It is of fundamental importance in various applications such as in communications, Doppler radar, synthetic aperture radar (SAR), array processing, radio frequency identification (RFID), resonance sensor, etc. The requirement on the performance of the frequency e...
