gold-MUSIC: A Variation on MUSIC to Accurately Determine Peaks of the Spectrum

Autor: Shridhar Venkatanarasimhan, K.V. Rangarao

Publikováno v: IEEE Transactions on Antennas and Propagation. 61:2263-2268

This paper presents a new way of accurately determining peaks of the MUSIC (“Multiple emitter location and signal parameter estimation,” R. O. Schmidt, IEEE Trans. Antennas and Propagation, vol. AP-34, no. 3, pp. 276–280, Mar. 1986) spectrum, h

gold-Fourier Kaluri method for estimating vortex shedding frequency

Autor: K.V. Rangarao, Venugopal Arumuru

Publikováno v: 2016 IEEE Region 10 Symposium (TENSYMP).

In this paper we present a compuationally lean method combining parameter estimation along with Fourier technique with an elegant gold section univariate minimization technique, in estimating the frequency. Simple parameter estimation technique in th

On the impulse response of a discrete-time linear IIR system

Autor: Ranjan K. Mallik, K.V. Rangarao

Publikováno v: Digital Signal Processing. 13:128-143

An explicit formula for the impulse response of a discrete-time causal linear time-varying infinite-impulse-response system in terms of the system parameters is obtained from the solution of a linear difference equation with variable coefficients. Th

Suppression of multiple narrow-band interference using real-time adaptive notch filters

Autor: H.H. Loomis, Michael A. Soderstrand, K.V. Rangarao, T.G. Johnson, R.H. Strandberg

Publikováno v: IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing. 44:217-225

The process of detection of narrow-band interference to a broad-band signal in a noisy environment using adaptive filtering techniques attributable to Kwan and Martin (1989) is further refined by modifying the gradient-search algorithm to reduce hard

A robust BFSK signal demodulator using orthogonal decomposer

Autor: T. Kaushik Reddy, Shaik Shakira Begum, K.V. Rangarao

Publikováno v: 2013 IEEE/AIAA 32nd Digital Avionics Systems Conference (DASC).

In this paper we present a new technique for detecting Binary Frequency Shift Keying(BFSK) signal using an Orthogonal Decomposer. Present techniques for detecting BFSK signal either require the knowledge of mark and space frequencies or estimate them

Estimating the directions of arrival of narrow band signals using Spatial Tuned Filter

Autor: K.V. Rangarao, Shridhar Venkatanarasimhan, V. Prathyusha, T. Neela Pavani

Publikováno v: Proceedings of 2011 IEEE CIE International Conference on Radar.

In this paper, we present a novel way of estimating the direction of arrival (DOA) of narrow band signals using beam-steering technique. The coefficients for steering the beam are derived using a second order autoregressive (AR) narrow-band filter. M
