OFDM parameter design of a digital broadcasting system in FM band
A thorough OFDM parameter design method of a digital broadcasting system in FM band is presented in this paper.Key OFDM parameters are analyzed from their constraints.Cyclic prefix should satisfy the requirement of channel delay and formation of SFN.Design of system bandwidth should consider coherent bandwidth and existing frequency planning.Symbol duration is restricted by time selectivity and frequency selectivity of the channel,and also efficient SINR should be maximized.System simulation is performed to test and verify the parameters under typical FM band channels.A set of OFDM parameter is provided for future design.
