Anti-fading mobile signal transmission method for digital broadcast single frequency network

Abstract

The invention discloses an anti-fading mobile signal transmission method for a digital broadcast single frequency network, and relates to a mixed framing modulation scheme of the space domain, the time domain and the frequency domain. According to the training sequence optimization design, the signal generating scheme and the signal selecting method of the anti-fading mobile signal transmission method for the digital broadcast single frequency network, OFDM signals can be processed and recovered at a receiver end easily to obtain original signals of the OFDM signals. The anti-fading mobile signal transmission method for the digital broadcast single frequency network has the advantages of being low in peak-to-average power ratio, short in synchronization time, resistant to channel fading, multiple in controllable service and the like.
