Summary:OFDM is nearly 100 percent efficient when it comes to capturing energy in a multipath environment. It does this through the use of fast Fourier transform (FFT) algorithms, which have the added benefit of comparatively low complexity. OFDM is a well-proven technique in many other high-performance commercial communications systems (for example, IEEE 802.11a/g, 802.16a, ADSL, VDSL and HomePlug). MBOA systems transmit data on each of the sub-bands by using 128 tones that are situated 4.125 MHz apart.
