摘要
UWB(Ultra-WideBand)作为一种具有强大商业价值和发展前景的通信传输技术,业界对于超宽带发射与接收系统的研究也相当重视。文中提出了一种新的UWB混合调制方式,在信道条件较好的情况下可以成倍提高信息的传输速率。该方法将传统的幅度调制与跳时调制相结合,对传输信号进行2次调制,以携带更多的信息。
A new method for UWBMixed Modification is proposed, by which transmission rate can be greatly raised under good channel condition. In combination of traditional amplitude modification and time-hopping modification, this method modulates twice the transmission signals, thus more information can be provided.
