Performance analysis of modulation schemes in Intra Vehicle Communications (IVC) channel

Recently Intra Vehicle Communication received great interest from the automotive industry and Ultra Wideband (UWB) technology considered as one of the potential candidate for this system. Goal of this paper is to compare UWB pulse modulation schemes like time hopping pulse position modulation (TH-PPM), direct sequence pulse amplitude modulation (DS-PAM) and multi-band orthogonal frequency division multiplexing (MB-OFDM) under intra vehicle communication (IVC) channel environment and find best suited modulation scheme for in-vehicle communication system. Vehicular channel model which is used for this paper was developed on the basis of IEEE 802.15.3a indoor channel model with modification in propagation environment. Through simulation BER performance of modulation schemes are evaluated.
