    Abstract: An AM simulcast broadcast signal combining a digital transmission signal and an analogue transmission signal in one transmission channel. The digital transmission signal is modulated to one sideband of a carrier of the transmission channel and a correcting signal (C) is modulated to the other sideband of the carrier of the transmission channel, which correcting signal (C) is determined so that the envelope demodulation of the transmission channel represents the analogue transmission signal.

    Abstract: A system for peak-to-average-power ratio (PAPR) reduction of a frequency shifted plurality of digital broadcast signals taking into account the combined signal peaks in order to transmit the signals more efficiently in a single broadcast transmission system. The PAPR algorithm takes into account a rotating constellation phase offset for the shifted signals corresponding to the amount of applied frequency shift. In the case of a dual sideband In-Band-On-Channel (IBOC) signal typically used in conjunction with an FM carrier in the center, the sidebands can be interleaved to create a new IBOC signal definition and take the place of the FM carrier for an all-digital transmission that is backward compatible with IBOC receivers allowing for a gradual migration to all digital broadcasting.

    Abstract translation: 考虑到组合信号峰值的频移多个数字广播信号的峰值与平均功率比（PAPR）的系统，以便在单个广播传输系统中更有效地发送信号。 PAPR算法考虑了与所施加的频移量相对应的移位信号的旋转星座相位偏移。 在通常与中心的FM载波一起使用的双边带带内通道（IBOC）信号的情况下，边带可以被交织以产生新的IBOC信号定义并代替FM载波 用于与IBOC接收机向后兼容的全数字传输，允许逐渐迁移到所有数字广播。
