    • The present invention provides a signal modulation method which includes the following steps: a input signal is channel encoded, and the channel encoded signal is processed by the following one or several ways: channel scrambling, interleaving, duplicating and puncturing; the signal being processed is divided into two components I and Q, wherein the two components I and Q compose a signal pair; the signal pair is divided into more than one path, and respective path of signal is quadrature phase shift keying spectrum spreading modulated using different spectrum spreading sequence and is orthogonally modulated in order that the peak-to-average power ratio of the respective paths of signal being orthogonally modulated are obtained; and a path of signal having the smallest peak-to-average power ratio is selected to be outputted as an output signal. The signal modulation method can reduce the signal PAPR significantly, not only is propitious to the design of the power amplifier, but also reduces the cost of the power amplifier.
    • 本发明提供了一种信号调制方法,包括以下步骤:输入信号被信道编码,并且通过以下一种或多种方式对信道编码信号进行处理:信道加扰,交织,复制和穿孔; 被处理的信号被分成两个分量I和Q,其中两个分量I和Q组成信号对; 信号对被划分成多于一个路径,并且信号的相应路径是使用不同的频谱扩展序列进行正交相移键控频谱扩展调制,并且被正交调制,以便各信号路径的峰值与平均功率比 获得正交调制; 选择具有最小峰值功率比的信号路径作为输出信号输出。 信号调制方法可以显着降低信号PAPR,不仅有利于功率放大器的设计,而且降低了功率放大器的成本。
