Abstract

The present invention relates to a frame structure suitable for E-band communication, comprising a frame preamble, a frame header and several data blocks arranged in sequence, the frame preamble includes a cyclic prefix for combating multipath interference and eliminating intersymbol interference and for Timing synchronization, channel estimation and frequency offset estimation compensation training sequence; the frame header includes a modulation mode part, a link quality part, a data block number part, a CRC check part, a reserved part and a pilot part, wherein the modulation mode part It is used to determine the mapping method of the data in this frame, the link quality part is used to indicate the information transmission environment, the data block number part is used to indicate the data information length in this frame, and the CRC check part is used to enhance the resistance of the frame header data. Interference capability, the reserved part is used to expand and upgrade the frame structure, and the pilot part is used for frequency offset tracking and compensation. The invention can adaptively modulate the modulation mode of the information data according to the communication environment, and realize various transmission rates of the system.

Description

technical field [0001] The invention relates to the technical field of E-band wireless communication, in particular to a frame structure suitable for E-band communication. Background technique [0002] According to the division of CCIR (Consultative Committee of International Radio), the E-band refers to electromagnetic waves with communication frequencies of 71G-76GHz and 81G-86GHz. Using E-band for wireless communication is called E-band wireless communication. [0003] The popularization of multimedia terminals and applications such as high-definition digital services have led to an increasingly serious problem of shortage of frequency resources in wireless communication systems. In order to increase the transmission rate, OFDM can be used in traditional short-wave and microwave communication, and solutions such as constructing heterogeneous networks can be used. However, due to factors such as available spectrum width and receiver complexity, the communication capacity...

Problems solved by technology

The received signal of the receiver contains multipath waves that experience attenuation and time delay, and serious interference will occur between signal symbols, which will cause the receiver to fail to demodulate the data normally.

If time-domain equalization is used at the receiving end to reduce the impact of inter-symbol interference, more filter taps are needed to obtain the equalization effect that meets the system requirements, and the overhead and system implementation complexity of the entire system equalization are very large
