One kind of new MB-OFDM-UWB technical analysis and application
Friday, November 21st, 2008 at 08:19 | No commentsCategories: Communication NetworksShort Content: 1 introduction The ultra-wide band (UWB) communication has the high speed, the high performance, the low power loss, the low cost, the anti-multi-diameters to decline, the easy digitization and so on many merits. In the Internet, multimedia and wireless communication technology fusion today, it is realizes in the small scope the seamless cover wireless multimedia transmission demand popular technological means that regards as the new generation wireless territory net physics level standard technology. At present UWB has two big ... -
In the ultra-wide band wireless communication the LDPC code hardware simulation realizes - en.51rd.net
Friday, November 21st, 2008 at 06:05 | No commentsCategories: Communication NetworksShort Content: 1 introduction The code length long low speed LDPC code presents the superiority which in the signal-to-noise ratio low application situation other codes are unable to be a worthy opponent, already proved that the non-rule the LDPC code performance even surpasses Turbo the code high speed LDPC code performance quite to be also good. Especially in the magnetic recording and so on some application situation, the code length short high speed LDPC code has the broader application prospect. In ... -
One kind of structure simple UWB receiver’s design with realizes - en.51rd.net
Friday, October 17th, 2008 at 22:14 | No commentsCategories: Communication NetworksShort Content: Introduction At present, the ultra-wide band (UWB) demodulation method may induce into the following three kinds: One kind is constructs one with the received signal similar template signal, then selects the related method; Other one kind is uses the integral detection the way to demodulate the UWB signal; Also one kind is carries on A/D to the receive signal to transform, through sampling value identification signal. The first kind of plan realizes is quite difficult, because ns level pulse, if realizes ...
