Design of Grey Wolf Optimizer based Amended Equalizer for Universal Mobile Telecommunications System

In equalization scheme the setback of falsification is suffered by any signal when it is transmitted through some communication media. An exhaustive research has been carried out on Amended Equalizers (AEs) and their application in contemporary communication system since last two decades. On the other hand research has also been carried out not only for developing nature based efficient meta-heuristic algorithms but also enhancing the performance of communication systems using the proposed algorithms. In this article, an improved version of equalizer has been designed using Grey Wolf Optimizer (GWO) algorithm. Moreover, non-bijective modulation scheme named superposition modulation outline has also been incorporated within the proposed model. Now the comparative convergence act along with Bit Error Rate (BER) of the proposed Grey Wolf Optimizer (GWO) triggered Amended Equalizer (AE) has been investigated. For this purpose numerous classical algorithms like Constant Modulus Algorithms (CMA) and Least Mean Square (LMS) algorithm have also been considered and finally the behavior of the proposed equalizer has been assessed in Universal Mobile Telecommunications System (UMTS).
