WiFi and WiMAX are the well developed and standardized technologies working on OFDM platform. Their physical layer architecture are much similar accept WiMAX physical layer has RS encoder & decoder at transmitter and receiver respectively. WiFi and WiMAX are widely used wireless technologies for accessing internet. This paper elaborates the implementation of unified physical layers of WiFi and WiMAX technologies which are compliant to IEEE standards 802.11a and 802.16a respectively. The PHY specifications of these standards are described with block schematics. The scope of this paper is limited to the digital signal processing involved in the PHY layers of WiFi and WIMAX technologies.
