产生高速信道的方法和系统
摘要：
本发明揭示了一种产生由一组较低速率的信道组成的减小峰值幅度的高数据速率信道的新的、改进的方法和装置。该组较低速率的信道(90，92)在相加和传送前经相位旋转。相位的旋转量取决于用来形成更高速率信道(102)的信道数。在一种采用较低速率的信道(90，92)的实施例中，两个信道的同相和正交相分量在用同相和正交相正弦信号上变频之前进行复数乘。对于由两个以上的较低速率的信道组成的高速信道，每一个信道的同相和正交相分量用相位相互偏移的一组正弦信号上变频。
摘要（英）：

The invention discloses a novel and improved method and apparatus for generating a reduced peak amplitude high data rate channel comprised of a set of lower rate channels The set of lower rate channels (90, 92) are phase rotated before being summed and transmitted. The amount of phase rotation is dependent on the number of channels used to form the higher rate channel (102). In an embodiment wheretwo lower rate channels (90, 92) are used, the in-phase and quadrature-phase components of the two channels are complex multiplied before upconversion with an in-phase and quadrature-phase sinusoids.For a high rate channel comprised of more than two lower rate channels, the in-phase and quadrature-phase component of each channel is upconverted with a set of sinusoids that are phase offset from one another.
