Metaheuristic approaches to enhance of dm system performance for high speed wireless applications

Abstract

Today the wireless communication and technology serve a vitalplatform for carrying a large amount of digital data across the globe. Its rapidpace of development facilitates highly smooth and very efficient performanceof industries of all discipline. Every small, medium, and large scaleenterprises rely upon deployment of wireless technology infrastructure tocope up with both local and global business scenario. In future years,wireless technology enables highly sophisticated devices with outstandingfeatures. For example the 4G technology brings broad band high rate dataservices by which every gadget and human stay connected featuring lowlatency, high power conservation, and lively feel of information exchange.OFDM plays a pivotal role in wireless communications due to its high datarate handling ability and robustness to frequency selective fading channels.OFDM in high speed wireless applications is an essential signal processingtechnique for the forthcoming decades due to its high speed compatibility.The demand for high speed applications increases due to availability oflimited bandwidth source. Not only wired applications but also wirelessapplications usage increases day by day as emerging trends innovates newdevices. These results in high data rate requirement and hence increase innumber of sub-carriers. This creates issue with the Peak to Average PowerRatio (PAPR). newline
