摘要 针对传统正交频分复用(OFDM)系统的功率效率问题,文章给出一种新的基于添零方式的载波干涉正交频分复用(ZP-CI/OFDM)无线传输技术。ZP-CI/OFDM通过载波干涉码将发射符号扩展到所有OFDM子载波上,在有效消除传统OFDM面临的峰值平均功率比问题的同时,充分利用多载波的频率分集增益;同时,ZP-CI/OFDM通过在发射端添零,采用先进的接收机技术进一步利用频率分集增益,提高系统的功率效率。 Low power efficiency is a problem affecting traditional Orthogonal Frequency Division Multiplexing （OFDM） systems. To counter this problem, a new wireless transmission technology based on zero-padding interferometry OFDM （ZP-CI/OFDM） can be employed. ZP-CI/OFDM extends the launch symbol to all OFDM subcarriers via carrier interfermoetry codes, eliminating the average power ratio problem and making full use of multicarrier frequency diversity gain. Through zero-padding at the transmitter, ZP-CI/OFDM can use an advanced receiver to take further advantage of diversity gain and to improve power efficiency in the system.
