In this paper, a simple and efficient Block and partial update sign normalized LMS (BPSNLMS) algorithm is proposed for the decision feedback equalization. The proposed implementation is suitable for applications requiring long adaptive equalizers, as is the case in several high-speed wireless communication systems. The proposed algorithm yields good bit error rate performance over a reasonable signal...
Decision feedback equalizers are used in wireless and mobile communications to reduce the intersymbol interference that is caused by the time dispersive channel. Here, an adaptive decision feedback equalizer is presented with a new adaptive algorithm. The algorithm uses sign normalized block based least mean square algorithm, and achieves a significant reduction of computational complexity. The proposed...
Swarm based intelligent search algorithms are heuristic search methods whose mechanics are inspired by the swarming or collaborative behavior of biological populations. This paper proposes a new swarm based algorithm called LBEST PSO with dynamically varying sub-swarms (LPSO_DVS). The performance of four swarm based intelligent search algorithms Particle Swarm Optimization (PSO), Fitness Distance...
