Performance evaluation of a WIMAX system using coding technique

This paper provide wireless digital communications system, also known as IEEE 802.16, that is intended for wireless metropolitan area networks. WIMAX can provide broadband wireless access (BWA) up to 30 miles for fixed stations, and 3 - 10 miles for mobile stations. The name was created by the WiMAX Forum. The forum describes WiMAX as a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL[1]. The major drawback of WIMAX system is high BER and as BER increases, signal to noise ratio decreases. It means, the less the BER, result is the higher the SNR and the better communication quality This paper presents simulation of WiMAX using OFDM technique using coding technique. BER versus Eb/No curves are used for comparing the results.
