The invention discloses a robust multi-media mobile broadcast signal framing modulation method which is a framing modulation scheme of mixing a time domain and a frequency domain. According to the robust multi-media mobile broadcast signal framing modulation method disclosed by the invention, a low-complexity peak-to-average power ratio reduction technology and a combined code modulation technology are designed aiming at the technical problems of high signal peak-to-average power ratio, channel time variant, Doppler frequency shift and noise of a broadband multi-carrier multi-media mobile broadcast system, which need to be solved, and therefore the broadband multi-carrier multi-media mobile broadcast system has the advantages of low peak-to-average power ratio, short synchronization time,robustness, controllable multi-service, and the like.
