Time-delay estimation performance in a scattering medium 

Prasad, S; Narayanan, M; Desai, S (1985)
The effects of a scattering medium on the performance of time-delay estimation are considered. The medium is assumed to exhibit angular scattering, causing angular (as well as delay) dispersion and hence loss of signal ...

Finite lag receivers for analog communication 

Prasad, S; Mahalanabis, A (1975)
The problem of designing optimum receivers with a finite built-in delay, for a class of stochastic signals, is considered. The approach used here is based on the so-called fixed-lag smoothing techniques. Specific cases of ...

On optimum receivers for analog communication in impulsive noise 

Madan, B; Prasad, S; Mahalanabis, A (1978)
In this paper the problem of impulsive noise suppression in analog communication systems is considered. The problem of demodulation of amplitude and phase modulated signals in the presence of impulsive noise is formulated ...

Linear antenna arrays with broad nulls with applications to adaptive arrays 

Prasad, S (1979)
The problem of designing a class of linear antenna arrays with broad nulls against interfering signals of variable direction of arrival is considered. The problem is formulated in an appropriate signal space selected for ...

A novel theorem with potential application to automatic equalization 

Prasad, S (1979)
When the signs of the alternate terms of a symmetric discrete time series are reversed and the resultant series is convolved with the original, the newly created time series will have alternate values equal to zero. This ...

On the index for array optimization and the discrete prolate spheroidal functions 

Prasad, S (1982)
A class of array optimization problems is considered in which we seek to optimize the array response in a specified angular sector. The optimization of array directivity is shown to be a special limiting case of these ...

DOA estimation of wideband sources using a harmonic source model and uniform linear array 

Agrawal, M; Prasad, S (1999)
We consider the problem of estimation of the DOAs of multiple wideband sources incident on a uniform linear array (ULA) in the presence of spatially and temporally white Gaussian noise (WGN). The approach presented builds ...

Improved FIR filters for discrimination of damped sinusoids 

Agrawal, Monika; Prasad, S; Roy, S C Dutta (1997)
It is shown that the FIR filter based discrimination of damped sinusoids can be improved by removing the linear phase constraint. The resulting filter is not only economical and better suited to processing of shorter data ...

Modified constant modulus algorithm for blind DS/CDMA detection 

Al-Bayati, A K S; Prasad, S (1999)
A new blind adaptive multiuser detector for synchronous DS/CDMA systems based on a modified constant modulus algorithm is proposed. This detector is shown to outperform the minimum output energy detector in a downlink ...

Blind space-time constrained minimum variance detection of DS/CDMA signals 

Al-Bayati, A K S; Prakriya, S; Prasad, S (2002)
Constrained minimum variance (CMV) detection has been proposed for blind multiuser detection of DS/CDMA signals in multipath channels. We suggest a new approach for implementing the CMV detection when an antenna array is ...
