We propose a convex combination of two blind equalizers adapted respectively by CMA (constant modulus algorithm) and SWA (Shalvi-Weinstien algorithm). The performance of the proposed scheme is, in the worst case, as good as that of the best of its components. This behavior provides a good tracking capability, since both CMA or SWA may have a better tracking performance, depending on the kind of nonstationary environment. A steady-state analysis (using energy conservation) is also presented, considering both the proposed scheme, and the convex combination of two CMAs.

Blind beamforming has been studied extensively in recent times. Array signal processing is an effective technique for signal extraction in communication systems. We employ minimum entropy deconvolution(MED) principle for source extraction. Results are shown which indicate good performance in comparison with conventional adaptive algorithms like the constant modulus algorithm and the multi-modulus algorithm.

A robust blind multiuser receiver based on a linearly constrained constant modulus algorithm (LCCMA) with multiple constraints and Quadratic Inequality (QI) constraint on the weight vector norm is developed in this paper. Quadratic constraints have been a prevalent approach to improve the robustness against mismatch and modeling errors, uncertainties in estimating the data autocovariance matrix, and random perturbations in detector parameters. In this paper, the LCCMA is realized using a fast steepest descent adaptive algorithm based on the partition linear interference canceller (PLIC) structure with multiple constraints and a QI constraint on the weight vector norm. The Lagrange multiplier methodology is exploited to solve the QI constraint problem. Simulations are carried out in a loaded multipath environment with near-far effect to validate the robustness of the proposed detector.

During transmission of signal through a channel the signal becomes distorted noise and the transmitted signal also suffers from Inter Symbol Interference (ISI). Adaptive Equalizers (AEs) are used to reduce the ISI and the noise by updating the filter coefficients without having the prior information about the noise. So the necessity of designing more efficient adaptive filters has been emerged as one of the interesting research areas over last decades. In recent past some optimization techniques have been developed which provide better results than conventional Adaptive Equalizers (AEs). In this context, an attempt has been made to explore some efficient AEs based on the intelligent computational techniques. Three optimization techniques namely Harmony Search (HS), Cuckoo Search (CS) and Flower Pollination algorithm (FPA) have been used in this paper. Moreover, the comparative analysis of the convergence behavior and BER performances of the proposed AEs have been investigated and also compared with Least Mean Square (LMS) algorithms and constant modulus algorithms (CMA) based AEs. Furthermore, performance analysis of the proposed AEs under different fading channel conditions like Rayleigh, Rician and Nakagami Fading have also been studied. Finally, the performances of the proposed equalizers have been evaluated in WiMAX system.

Blind channel equalization for GFDM systems based on a constant modulus algorithm (CMA) is proposed in this paper. The system implements CMA together with a discrete Fourier transform (DFT) that enables the realization of blind equalizer which is comparable to pilot based system. Two performance parameters are used to evaluate the equalizer, first is the symbol error rate (SER) and second is the mean squared error (MSE). The obtained results from simulation show that the performance of the proposed system is better than that of pilot-based system. The result also indicates that its performace closely matches to the ideal estimation and equalization of the channel.

In this paper, we address the problem of identifying the modulation level of the received signal under an unknown frequency selective channel. The modulation level classification is performed using reduced-complexity Kuiper (rcK) test which utilizes the distribution of signal features such as magnitude of the received samples or phase difference in consecutive received samples. However, in frequency selective channels, these features are severely distorted resulting in a poor classification performance. We propose to use constant modulus algorithm (CMA) to mitigate the impact of the frequency selective channel on the signal feature. Simulation and analytical results show that the proposed CMA-rcK technique outperforms state-of-the-art cumulant-based technique as well as blind equalizer-based technique that uses Alphabet Matched algorithm.

Concurrent Blind Equalization Suitable for 16-QAM Signal

Concurrent Blind Equalization Suitable for 16-QAM Signal

International Conference on Wireless Communications and Signal Processing

A new concurrent scheme for blind equalization suitable for 16-QAM signal is proposed. It combines Modified modulus algorithm (MCMA) and Modified Decision Directed (MDD) algorithm. By exploiting the inherent structural relationship between the 4-QAM signal's coordinates and 16-QAM signals' coordinates, another style of cost function for constant modulus algorithm (CMA) is defined, and we have proved that MCMA with such cost function outperforms the conventional CMA considerably. Unfortunately, MCMA has the same inherent defect as CMA which is that it is not sensitivity for phase offset of received signals. So when it occurs, the performance of MCMA will be impaired and even MCMA cannot work. Accordingly for overcoming the shortcomings of MCMA we introduce the Decision Directed (DD) algorithm, and modify it with the same method as MCMA. Consequently the new concurrent blind equalization with MCMA and MUD is proposed. Simulation results with underwater acoustic channel model show that the proposed algorithm achieves satisfactory performance.

The error function is important for the blind equalizer based on neural networks to adaptively adjust its parameters. Aiming at finding a new error function, the paper studied the square contour algorithm (SCA) and the complex backward propagation neural networks (CBPNN). The properties of the equalizers based on the cost function of SCA were simulated, and comparison was made with that of CMA. Results show that the equalizer with cost function of SCA converges slower and the byte-error rate (BER) is greater than that of CMA. The residual errors are the same because the cost function only varies in appearance. Therefore, in designing the equalizer based on CBPNN, it is not advisable to replace the error function of CMA with that of SCA.
