Adaptive Modulation Techniques for Duplex OFDM Transmission

, 2000
The design tradeoffs of turbo-coded burst-by-burst adaptive orthogonal frequency division multiplex (OFDM) wide-band transceivers are analyzed. We demonstrate that upon aiming for a higher throughput a higher proportion of low-quality OFDM subcarriers ...

OFDM synchronizer implementation for an IEEE 802.11(a) compliant modem

, 2002
In OFDM transmissions, synchronization arises to be one of the most critical operations. The reason for that is the preservation of orthogonality: timing offsets and frequency offsets destroy easily this orthogonality, leading to Inter-Symbol ...
