OFDM Based WLAN Systems
Overview Orthogonal Frequency Division Multiplexing (OFDM) is a special form of multi-carrier transmission where all the subcarriers are orthogonal to each other. OFDM promises a higher user data rate and great resilience to severe signal fading effects of the wireless channel at a reasonable level of implementation complexity. IEEE 802.11a and HiperLAN/2 have the capability to operate in a range of a few tens of meters in typical office space environment. This paper attempts to connect the different strings of OFDM and create a comprehensive reference. The paper attempts to provide an understanding of OFDM system along with a description of the challenges and research areas for enhancing system capacity and improving link quality.
