- Look for Power Tradeoffs in 10GBASE-T Ethernet
- IEEE 802.3, a 10GBASE-T Ethernet standard ratified in June 2006 following four years of development, is considered a mature and worthy successor to the 100BASE-T and 1000BASE-T standards, which were ratified in 1995 and 1999, respectively. The marketplace is ready for a speed upshift from the network: commodity servers have...

- An Efficient Implementation of NC-OFDM Transceivers for Cognitive Radios
- This paper presents an efficient implementation of a Non-Contiguous Orthogonal Frequency Division Multiplexing (NC- OFDM) transceiver for cognitive radio systems. NC-OFDM is designed to transmit information in the presence of incumbent users, deactivating subcarriers located in the vicinity of these users to avoid interference. Given that the core component of...

- Measured Data Rate From Adaptive Modulation in Wideband OFDM Systems
- Adaptive modulation is implemented on a wideband OFDM transceiver prototype to quantify its performance in indoor wireless environment. The measurements indicate that over a bandwidth of 100 MHz, the channel varies quite significantly. With a target uncoded Bit Error Rate of 10-3, it is found that at link distances of...
