[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

Embodiment Construction
[0062] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.
[0063] To improve the robustness of signaling frame transmission, first, repeat the scrambled signaling frame before forward error correction coding, or perform repetition plus inversion, or change the position of padding 0 after repetition, or After repeated addition and inversion, the positions filled with 0 are changed to generate a new signaling frame; then, the generated new signaling frame is sent.
[0064] Means for improving the robustness of signaling frame transmission, including:

The invention discloses a method and device for improving the robustness of signaling frame transmission. The method is: repeating the scrambled signaling frame before forward error correction coding, or performing repetition plus inversion, or repeating Change the position where 0 is filled, or change the position where 0 is filled after repeated addition and inversion, so as to generate a new signaling frame. The device includes: a processing system, which is used to repeat the scrambled signaling frame before forward error correction encoding, or perform repetition plus inversion, or change the position of filling 0 after repetition, or repeat addition and inversion Change the position filled with 0, generate a new signaling frame, and transmit it to the encoding module of the transmitter; the receiver must first decode the signaling frame when it receives it, and then according to the method of repetition or repetition plus negation and filling when sending In the position of 0, L-bit signaling frame b is restored. The present invention improves the reliability of signaling frame transmission by utilizing the diversity gain brought by the mapping of the short-bit signaling frame to the long-bit forward error correction coding input.
