What is WiMAX (OFDM)?

WiMAX – What is WiMAX? OFDM belongs to a family of transmission schemes called multicarrier modulation, which is based on the idea of dividing a given high-bit-rate data stream into several parallel lower bit-rate streams and modulating each stream on separate carriers, often called subcarriers or tones.

What is OFDM modulation?

OFDM is turning into the chosen modulation technique for wireless communication to reduce multipath fading effects and to provide massive data rates. OFDM is a multicarrier transmission system that utilizes the method of ripping smaller subcarriers of frequencies to agitate multipath drawback.

Is WiMAX technology facing hurdles?

CONCLUSION WiMAX Technology is facing many hurdles in market while it has some great advantages which make it a technology of today. This paper provided the quick and technical overview of concept, technology, standard, and architecture for IEEE 802.16 WiMAX. REFERENCES

What is OFDM (orthogonal frequency division multiplexing)?

It is shown that the combination of OFDM (orthogonal frequency-division multiplexing) techniques and concatenated codes provides an elegant solution to the problem of transmitting high rates (&ap4.7 Mb/s) in a channel that is strongly affected by multipaths (delay spread up to 16 μs)
