| dc.description.abstract | In recent years, people’s dependence on the Internet has caused
the Internet and life to become more and more closely connected, and
WiFi and mobile networks have also been introduced. Therefore, the
research and understanding of wifi is very important! The new generation
of Wi-Fi that is more popular today is Wi-Fi 6, also known as ”5G Wi-Fi”, because in the past Wi-Fi generally used the 2.4GHz frequency band,
but now it can operate at a higher frequency band of 5GHz, making The
stability is improved, and Ofdma also increases the transmission rate.
This paper will focus on the study of Wi-Fi 6, which is the 802.11ax
specification, to simulate a complete transceiver. It will also use the
software-defined radio platform (SDR) to perform transmission and reception
separately, to simulate the complete solution of the signal in a
real channel. During the tuning process, the maximum number of antennas provided is four times four. In addition to the complete system simulation, this paper will also discuss whether the use of space-time block
codes (Space-time block code, abbreviated as STBC) at the transmitter
has any impact on the demodulation results. Impact.
With people’s active investment in wireless communication research,
Wi-Fi 7 will come out in 2023. This paper will also briefly introduce the
differences between Wi-Fi 7 and Wi-Fi 6, as well as the main development points. We look forward to major breakthroughs in future technologies that will once again lead people into the next Wi-Fi generation | en_US |
