Dynamic Spectrum Sensing in LTE System for Better BER

摘要

In wireless communication system, there are many techniques present to obtain a communication. The generation of cellular networks have been developed drastically due to the usage of the networks. The 3rd Generation Partnership project (3GPP) implemented upto third generation, due to high power consumption and high cost in constructing closer base station we need next generation. Long Term Evolution (LTE) is our fourth generation. LTE is the standard for wireless communication system, evolution of GSM/UMTS. LTE can provide a better experience to the cellular networking users. OFDM is a recently developed modulation technique, which provides a better transmission in a channel. This paper deals with the determination of better Bit Error Rate (BER), by using various modulation scheme with various input generators.
