Biwindowed Discrete Multitone Transceiver Design

A family of biwindowed discrete multitone (DMT) transceivers that provide both subchannel spectral containment at the transmitter and spectral selectivity at the receiver is proposed. These systems have the attractive feature that they provide spectral shaping at both ends of the transceiver without requiring the cyclic prefix to be longer than the order of the channel impulse response. The windows are designed in a channel independent manner …
