Abstract

Even though broadband signaling and reception is often employed in practice for communication over time- and frequency-dispersive channels, existing receiver designs do not fully exploit the advantage of broadband signaling. We introduce a framework for time-frequency processing that is dictated by a canonical characterization of linear dispersive channels and fully utilizes the advantage of broadband signaling. The framework is based on processing in a natural time-frequency subspace defined by orthogonal time-frequency shifted copies of the transmitted broadband waveform. It generalizes existing receivers and suggests new designs that promise substantially improved performance compared to existing systems.
色散信道上宽带信号的规范时频处理
尽管宽带信号和接收在实践中经常用于时间和频率分散信道的通信,但现有的接收器设计并没有充分利用宽带信号的优势。我们介绍了一个时频处理框架,该框架由线性色散信道的典型特征决定,并充分利用宽带信号的优势。该框架基于在固有时频子空间中的处理,该子空间由传输宽带波形的正交时频移副本定义。它概括了现有的接收器,并提出了与现有系统相比,有望大幅提高性能的新设计。
