8.4. Case Study: Hiperlan/2 Application
Our target application is the physical layer specification for high-performance radio local area network type 2 (Hiperlan/2), which targets professional and wireless local area network (WLAN) applications .
The Hiperlan/2 physical layer is based on the orthogonal frequency division multiplexing (OFDM) modulation scheme, which has been selected due to its improved performance on highly dispersive channels.
A key feature of the Hiperlan/2 physical layer is that it provides several physical layer modes with different coding rates and modulation schemes, as selected by the link adaptation mechanism. As a result, the data rate ranges from 6 to 54 Mbit/s, thus improving the radio link capabilities under ...
