Concatenated Codes Design for OFDM Based Wireless Local Area Networks
Overview Orthogonal Frequency Division Multiplexing, OFDM, technology is generally used in lots of high data-reception communication systems, such as Digital Audio Broadcasting (DAB), Power Line Communications (PLC), and satellite communication systems. In some WLAN specifications, e.g. IEEE 802.11a and HiperLAN in European, or WiMAX (i.e. IEEE 802.16e, 2005 for mobile edition) in metropolitan networks, OFDM techniques are also applied. The advantages of OFDM systems are high spectrum efficiency, longer symbol duration against Inter-Symbols Interference (ISI) effect in multi-path environments, and narrow transmission band of each sub-carrier within coherence bandwidth such that the communication channel can be viewed as flat and not frequency selective. In this paper, the authors constructed channel model according to IEEE 802.11a standard by MathWorks Simulink tool with Communication and Signal Processing Blocksets.
