    • A multicarrier transmission system uses a set of carriers spaced apart in frequency with a number of bits being assigned to each carrier. A transmitter has an input for receiving a data signal (2) for transmission and a mapper (14) arranged to map the received data signal into a set of complex data symbols, wherein each data symbol determines modulation of one carrier in a set of carriers which are spaced in frequency. A frequency domain-to-time domain transform stage (18) is arranged to convert the set of modulated carriers to a time-domain signal. A peak detector (26) arranged to detect when the time-domain signal exceeds a predetermined criterion. A constellation modifier (27) arranged to modify the constellation value of at least one of the carriers in the converted time-domain signal.
    • 多载波传输系统使用频率间隔开的一组载波,其中多个比特被分配给每个载波。 发射机具有用于接收用于传输的数据信号(2)的输入和用于将接收的数据信号映射成一组复数据符号的映射器(14),其中每个数据符号确定一组载波中的一个载波的调制 频率间隔。 频域到时域变换级(18)被布置成将该组调制载波转换为时域信号。 峰值检测器(26)被设置为检测时域信号何时超过预定标准。 星座修改器(27)被设置成修改转换的时域信号中的至少一个载波的星座值。
