The monumental success over the years, in wireless communication and mobile communication have overcome the challenges such as fading, multipath, interferences and spectrum limitations due to the advancement in the communication system with higher peak data rate with reduced latency thus most of research work are being focused from long term evolution (LTE) along with reduced delay, area and power consumption. Narrowband Internet of Things (NB-IoT) is an emerging domain with a vast range of applications. The conventional NB-IoT network uses orthogonal frequency division multiplexing (OFDM) for data transmission over the communication channel. LTE downlink physical layer has three control channels which are PCFICH, PDCCH, and PHICH uses in channel processing. The processing step involves scrambling, modulation, layer mapping, precoding and resource element mapping at the transmitter. The receiver end comprising of demapping from the source elements and detection of data occurs in physical downlink channels of LTE. 5G will make sure that, one can download an app of any MB in size at greater speed when compared with existing system. The entire scheme has been simulated using Model sim and realized in Plan Ahead Tool in Virtex 5 tool.
