Method and device for improving robustness of signaling frame transmission

Abstract

The invention discloses a method and device for improving robustness of signaling frame transmission. The method includes the steps that before forward error correction encoding, a scrambled signaling frame is repeated, or repeating and negation are carried out, or a position filling 0 in the signaling frame is changed after repetition, the position filling 0 in the signaling frame can be changed after repeating and negation, and accordingly a new signal frame is generated. The device comprises a processing system, the processing system is used for repeating the scrambled signaling frame, or carrying out repeating and negation, or changing the position filling 0 in the signaling frame after repetition or changing the position filling 0 in the signaling frame after repeating and negation to generate the new signaling frame before forward error correction encoding and to transmit the new signaling frame to an encoding module of a transmitter; a receiver receives the signaling frame, decodes the signaling frame, and then restores a signaling frame b of an L bit according to the method of repetition or repeating and negation and the position filling 0 in sending. According to the method, diversity gain brought due to the fact that the signaling frame with a short bit is mapped into forward error correction encoding and input with a long bit, and reliability of signaling frame transmission is improved.

[0011] The length of the above signaling frame is much smaller than the number of input bits of the forward error correction code. If the signaling frame is mapped to the forward error correction code, if the method in the 60GHz frequency band IEEE802.11ad standard is used, the corresponding code cannot be well utilized. long coding gain or diversity gain
