DVB-H technology is based on ETSI standard designed to bring the broadcast services to battery-powered handheld receivers such as mobile. The system is defined based on the existing DVB-T (Terrestrial) system allowing for lesser power utilization, poorer signal power and speedy movements. DVB-H system uses OFDM technique to transport multimedia services in any of the three bandwidth modes i. e. 6, 7 and 8 MHz. In this paper, DVB-H physical layer is simulated using 4096 FFT mode and images are transmitted and received under AWGN channel. The main importance is on mapping methods, concentrating mainly on Hierarchical and Non-Hierarchical mapping methodologies. Bit error rate is analyzed for different code rates in both the type of methods and lastly concluded.
