Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) approach using UWB signals with short duration of pulses provide unique advantages in short-range high data rate WPAN physical layer applications, which include easy penetration through obstacles, high precision ranging and low processing power. Non-pulsed MB-OFDM system suffers from the frequency selectivity of the fading channels. MB-pulsed-OFDM is used eliminate heavy error correction coding for dense multipath frequency selective channel model. The IFFT module in the pulsed-OFDM transmitter is much less complex than the IFFT...
