| Summary: | Nowadays, the demand for multimedia wireless communication is growing extremely at a rapid pace and this trend is expected to continue in the future. The primary challenge is the demand for multimedia services accessed by many simultaneous users. A prominent example of this trend is orthogonal frequency division multiple access (OFDMA) technology. In addition, multiple input multiple output - orthogonal frequency division multiple access (MIMO-OFDMA) is combined to promote the benefits of simplicity, high performance system and exploitation of the multipath diversity which increases data rates and link reliability. Even though the OFDMA concept is simple in its basic principle, the design of a practical OFDMA system is far from being a trivial task. OFDMA is extremely sensitive to timing errors and carrier frequency offsets (FO) between the incoming waveform and the local references used for signal demodulation. |
