Abstract

The invention discloses an anti-noise multi-media mobile radio signal framing modulation method and relates to a hybrid framing modulation scheme of the time domain and the frequency domain. Due to the bit interleaved coded modulation mode, the training sequence optimization design, the signal generating scheme and the signal selection method of the anti-noise multi-media mobile radio signal framing modulation method, OFDM signals can be processed and recovered at a receiver end easily to obtain original signals of the OFDM signals, and the method has the advantages of being low in peak average power rate, short in synchronization time, resistant to channel fading, multiple in controllable service and the like.
