Abstract

The invention discloses a framing modulation method for robust multi-media mobile broadcast signals. The method is a framing modulation scheme with time domain and frequency domain mixed. According to the framing modulation method for the robust multi-media mobile broadcast signals, cascade interleaving code modulation is performed, training sequence optimization design is performed, signal generating modes are implemented, and a signal selecting method is implemented, so that original signals of OFDM signals are easy to obtain through processing and recovering at a receiver terminal, and the framing modulation method has the advantages of being low in peak-to-average power ratio, short in synchronization time and resistant to channel fading and providing multiple controllable services.
