Ultra wide bandwidth transmitter with tone grouping and spreading |
摘要 |
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.
