本文以线性时不变系统的特征信号、线性和循环分块卷积以及快速傅立叶变换等基本工具为基础,建立了一个系统的离散时间框架,并设计了适用于单用户和多用户无线多载波通信的新系统。单用户和多用户无线多载波通信是一个充满信号处理挑战的领域,在音频/视频广播、有线电视、调制解调器设计、多媒体服务、移动局域网和下一代宽带蜂窝系统等各种应用中具有巨大的潜力。
Relying on basic tools such as eigen-signals of linear time-invariant systems, linear and circular block convolution and Fast Fourier Transforms, this paper develops a systematic discrete-time framework and designs novel systems for singleand multi-user wireless multi-carrier communications — a field rich in signal processing challenges that holds great potential in various applications including audio/video broadcasting, cable television, modem design, multimedia services, mobile local area networks and future generation wideband cellular systems.
