The WIMAX OFDM waveform offers the advantage of being able to operate with larger delay spread of the NLOS environment.
The OFDM waveform eliminates the (ISI) problems and the complexities of adaptive equalization.
OFDM technology provides operators with an efficient means to overcome the challenges of NLOS propagation.
Recent international standards such as those set by IEEE802.16,ETSI BRAN and ETRI,have established OFDM as the preferred technology of choice.
It is easier to equalize the individual OFDM carrier than it is to equalize the broader signal carrier signal.
