Description
Summary:4G wireless communication systems use OFDM modulation technique in order to provide reliable transmission in a propagation area. Issues of this scheme related with data lossless, low BER, PAPR and well-synchronization are quite essential for emergency circumstances; especially in the natural disaster events, it is strictly required precise information transmission. In this manuscript, we mainly focus on performance of OFDM in the disaster management systems. Estimation of BER and PAPR in fading channels is superimposed by considering movement of objects in the disaster conditions.
