Title: 通信ネットワーク内の信号伝送方法、関連システム及び端末
IPC: H04B7/26
Filed: 2001-06-28
Abstract: 信号、特にデジタル信号を基地局（ＢＳ）のような所与の地点から移動通信ネットワーク端末（Ｔ）に伝送するための方法が、該端末（Ｔ）が所定の瞬間にパルス信号を発生することを想定する。基地局（ＢＳ）は、例えばマルチ経路伝播のような現象の結果として変化させられた受信波形を検出する。このように検出された波形は、例えば時間反転の形式の位相共役を受ける。基地局（ＢＳ）から端末（Ｔ）への伝送は、このようにして得られた位相共役波形に対応した波形を用いて行われる。このようにして、前述のパルス信号の波形に対応した波形が、端末（Ｔ）にて再構成できる。この再構成は、端末の地理的な所在地を基地局に追跡させる必要なく、かつ、周波数の再使用を可能にするために地理的領域を小区画に分割する必要もなく、端末（Ｔ）が占めている地理的な位置のみにて行われる。

IPC: A61B6/00
Filed: 2002-03-28
Abstract: In a data transmission system, and a method for transmitting data in the gigabit/second range, data are transferred from a source located on a rotary part to a stationary part via a slip ring system. A first gigabit data link proceeds from the source at the rotary part to a rotary module of the slip ring system, from which the data are transferred to a stationary module of the slip ring system. From the stationary module of the slip ring system, the data are transferred via a second data link to a receiver. Each of the rotary module and the stationary module of the slip ring system has a clock regenerator. The clock regenerators are operated to synchronize the gigabit/second data, proceeding from the first data link and proceeding to the second data link, to a stable reference clock, so as to prevent jitter from proceeding from the source to the receiver.
