Performance Study of the MCCDMA as Physical Layer for Mobile WiMAX Technology
Mobile WiMAX (Mobile Worldwide interoperability for Microwave Access), is a wireless broadband standard which promised high bandwidth over long-range transmission. It is OFDM-based technology that supports Point to Multi-Point (PMP) Broadband Wireless Access (BWA). Main application of mobile WiMAX today is for MAN/WAN base stations and link stations with both Line Of Sight (LOS) communication in the range of 10-66GHz (802.16c) and non-LOS communication in the range of 2-11GHz (802.16a & 802.16d. The major problem in the WiMAX system is that as the Bit Error Rate (BER) increase the Signal to Noise Ratio (SNR) decrease.
