Fixed-point error analysis of fast Hartley transform
K.M.M. Prabhu,S.B. Narayanan +1 more
TL;DR: In this paper, a fixed-point error analysis has been carried out for the fast Hartley transform (FHT) and the results are compared with the FFT error-analysis results.
Fixed-point error analysis of fast Hartley transform
TL;DR: The error-performance of radix-2 decimation-in-time and decimation -in-frequency form of the fast Hartley transform algorithm has been studied and the expressions obtained are similar to those obtained in the case of FFT for the corresponding cases.
Journal ArticleDOI
An improved LMS adaptive algorithm for narrowband interference suppression in direct sequence spread spectrum
P. Kalidas,K.M.M. Prabhu +1 more
TL;DR: In this article, a new adaptive least mean squares (LMS) algorithm to increase the slow convergence of their nonlinear adaptive filter is described. But the main drawback of their adaptive nonlinear filter is its slow convergence rate.
Journal ArticleDOI
Implementation of MTD-WVD on a TMS320C30 DSP processor
J. Giridhar,K.M.M. Prabhu +1 more
TL;DR: The implementation details of a WVD-based moving target detector (MTD) on a TMS320C30 floating-point digital signal processor and the probability of detection and false alarm curves have been presented to support the superiority of the proposed MTD-WVD overMTD-I.

FHT algorithm for length N=q.2/sup m/
N. Vijayakumar,K.M.M. Prabhu +1 more
TL;DR: Fast computation of the discrete Hartley transform of length N=q, where q is an odd integer, is proposed, giving rise to a substantial reduction in computational complexity when compared to other algorithms.
