摘要

Relying on basic tools such as eigensignals of linearntime-invariant systems, linear and circular block convolution, and fastnFourier transforms (FFTs), this article develops a systematicndiscrete-time framework and designs novel systems for single- andnmultiuser wireless multicarrier communications-a field rich in signalnprocessing challenges that holds great potential in various applicationsnincluding audio/video broadcasting, cable television, modem design,nmultimedia services, mobile local area networks, and future-generationnwideband cellular systems. Wireless multicarrier (MC) communicationnsystems utilize multiple complex exponentials as information-bearingncarriers. MC transmissions thus retain their shape and orthogonalitynwhen propagating through linear time-dispersive media, precisely asneigensignals do when they pass through linear time-invariant (LTI)nsystems
