IEEE 802.11n Implementation
7.1 IEEE 802.11n PHY Layer Introduction
Wi-Fi systems based on the IEEE 802.11 standards are widely deployed for both indoor and outdoor environments. It is well known that the Wi-Fi system suffers from the channel-fading phenomenon that degrades the link quality and limits the range of communication. Besides, the increasing demand for high-throughput brings new challenges to the existing systems.
As detailed in the preceding chapters, the studies show significant coding gain of Multiple-Input Multiple-Output (MIMO) technology compared with traditional SISO solution and many research works have been done to give a good space-time coding to make full use of the MIMO technique. Therefore, ...
