Implementation of a simulink model for 802.11 standard of wireless. This system will be implemented in simulink tool of Matlab and which will have transmitter and receiver with between them standard methodology used for data transmission and at receiver end there will be a analyzer block which will help us to analyze the performance of system on basis of parameters like ber, number of errors etc. The main goal of this Project work is to learn and understand the features of the IEEE standard 802.11a and afterwards, once familiarized with this standard, to develop an OFDM 802.11a PHY layer baseband implementation with the characteristics showed in such standard. Matlab/Simulink is used for designing the model.
