Pulse-Shaping OFDM/BFDM Systems for Time-Varying Channels: ISI/ICI Analysis, Optimal Pulse Design, and Efficient Implementation

Overview This paper considers practically relevant aspects and advantages of pulse-shaping Orthogonal/Biorthogonal Frequency Division Multiplexing (OFDM/BFDM) systems. This paper analyzes the InterSymbol/InterCarrier Interference (ISI/ICI) in such systems when they operate over time-varying channels. Two methods for an ISI/ICI-minimizing pulse design are proposed, and efficient FFT-based modulator and demodulator implementations are presented. Simulations show that for fast time-varying channels, optimized BFDM systems can outperform conventional OFDM systems with respect to ISI/ICI.

Ethernet promises cheaper broadband

The Ethernet uplink from the DSLAM can be run on a spare fibre or, using a separate wave division multiplexing box, on one already in use by the ATM network. Instead of adding more expensive ATM channels for new subscribers, they can be put onto...

Radioactive: Bluetooth - survival of the fastest

The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. This increases the signal's range by reducing interference. The former method, backed by Intel, is more complex: it chops up the...
