Title:
直交周波数分割多重変調を使用して超広帯域信号を通信する方法および送信機
Document Type and Number:
Japanese Patent JP4633054
Kind Code:
B2
Abstract:
A method and system communicates ultra wide bandwidth signals using orthogonal frequency division multiplexing modulation. QPSK input symbols are frequency interleaved. The frequency interleaved symbols are spread over a plurality of tones, and the tones are modulated for transmission over an ultra wide bandwidth channel. When the tones are received, the received tones can be de-spreaded to recover the input symbols.
