Orthogonal Frequency Division Multiplexing for Wireless Networks
Abstract
Orthogonal frequency division multiplexing(OFDM)
is one of the multicarrier technique that establish the transmission of data using number of subcarriers which enable high data rate due to the optimal usage of band width. The OFDM is the 5-GHz standard gives a speed up to 54Mbps in 802.11a as compare to other multicarrier technique .This paper implement the transceiver model and simulated using SIMULINK software according to the standard
parameter, then evaluated performance. To improve the system performance some consideration is taken to reduce disadvantages, forward error correction coding, synchronization and channel estimation and detection which results the high speed transmission along wireless network .Also analyze the level of application.
