Performance Enhancement of OFDM System With Pseudo Pilot Channel Estimation Using Hybrid Optimization Techniques

Abstract

There ia a revolution in wireless mobile communication with the arise of 4G and 5G newlinetechnology. In context of that the users are demanding new facilities such as they access newlineavailable frequency spectrum anywhere, anyplace and anytime. With the evolution of advanced communication network to accommodiate various types of communication systems under these technologies like Wi-Fi, WLAN, WiMAX, AM, FM, GSM, CDMA, LTE requires newlinebetter transmission in terms of signal to noise ratio or Bit instaneous energy to average noise power. At the same time it is expected that excellent data rate is to be maintain with low newlinelwvwl of bit error rate. newline
