Online adaptive reinitialization of the constant modulus algorithm

چکیده
An adaptive reinitialization algorithm for the constant modulus algorithm is proposed that relies on the similarities between the constant modulus and the Wiener equalizer and expands the capabilities of a previous algorithm. The proposed algorithm determines adaptively if the CMA will benefit through reinitialization, and if so, it will calculate new equalizer coefficients leading to the global minimum.

Blind Channel Equalization Using Constrained Generalized Pattern Search Optimization and Reinitialization Strategy
We propose a global convergence baud-spaced blind equalization method in this paper. This method is based on the application of both generalized pattern optimization and channel surfing reinitialization. The potentially used unimodal cost function relies on higherorder statistics, and its optimization is achieved using a pattern search algorithm. Since the convergence to the global minimum is n...
متن کاملThe MSE performance of constant modulus receivers
The constant modulus algorithm (CMA) is an e ective technique for blind receiver design in practice. Treating CMA as a linear estimation problem, e ects of noise and channel conditions are investigated. For the class of channels with arbitary nite impulse responses, an analytical description of locations of constant modulus receivers and an upper bound of their mean squared errors (MSE) are der...

A multi objective Honey Bee Mating Optimization (HBMO) designed by online learning mechanism is proposed in this paper to optimize the double Fuzzy-Lead-Lag (FLL) stabilizer parameters in order to improve low-frequency oscillations in a multi machine power system. The proposed double FLL stabilizer consists of a low pass filter and two fuzzy logic controllers whose parameters can be set by the ...
متن کاملA High Performance Blind Adaptive Filtering Algorithm
Recently a dithered signed-error constant modulus algorithm (DSE-CMA) has been proposed for the purpose of low complexity implementation of constant modulus algorithm (CMA), which is widely used for blind adaptive filtering due to its LMS-like desirable robustness properties. Despite the fact that this algorithm has robustness properties closely resembling those of CMA, it is very slow in conve...
متن کاملOnline Inertia Constant and Thévenin Equivalent Estimation Using PMU Data
In this paper a new algorithm based on phasor measurements for estimating the Thévenin Equivalent (TE) and system inertia constant is proposed. The method estimates the network TE seen from a generator terminal and equivalent system inertia constant by means of phasor data that is available at Phasor Data Concentrator (PDC) center. It is shown that the parameters of the TE could be estimated at...
