METHOD AND DEVICE FOR SETTING 2X EHT-STF SEQUENCE FOR WIDEBAND IN WIRELESS LAN SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18208013 Titled 'METHOD AND DEVICE FOR SETTING 2X EHT-STF SEQUENCE FOR WIDEBAND IN WIRELESS LAN SYSTEM'
Simplified Explanation
The abstract describes a method and device for receiving a PPDU (Physical Protocol Data Unit) in a wireless LAN system. The reception STA (Station) receives the PPDU from a transmission STA through a wideband and decodes it. The PPDU includes an STF (Short Training Field) signal, which is generated based on a first STF sequence for the wideband. In the case of a 320 MHz band, the first STF sequence is a specific sequence. The abstract provides the exact sequence but it is not necessary to include it in the simplified explanation. Finally, the abstract mentions a mathematical expression involving complex numbers, which is not necessary to include in the simplified explanation.
Original Abstract Submitted
Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives the PPDU from a transmission STA through a wideband and decodes the PPDU. The PPDU includes an STF signal. The STF signal is generated on the basis of a first STF sequence for the wideband. When the wideband is a 320 MHz band, the first STF sequence is a sequence including a M sequence and is defined as {M −1 M −1 −M −1 M 0 −M 1 M 1 −M 1 −M 0 M −1 M −1 −M −1 M 0 −M 1 M 1 −M 1 −M 0 −M 1 −M 1 M 1 −M 0 M −1 −M −1 M −1 M 0 −M 1 −M 1 −M 1 M 1 −M 0 M −1 −M −1 M −1 M}*(1+j)/sqrt(2).
