摘要

在多载波调制数据系统中，提出了一种新的调制解调器方案。调制解调器的特点:考虑在通信信道中不会引起符号间干扰的复杂、窄带、有限的信号，并对其进行时空处理。计算了调制解调器的光谱能量效率。实验结果表明，与标准的OFDM调制解调器相比，该调制解调器的效率得到了提高。

Multi-Carrier Modulations Digital Modem with the Narrow-Band Optimal Signals and High Spectral-Energy Efficiency

A new modem scheme has been developed in the multi-carrier modulation data system. Modem features: accounting of complex, narrow-band, finite signals that do not cause inter-symbolic interference in the communication channel, and space-time processing of them. The spectral-energy efficiency of the modem has been calculated. It is shown that the new modem has increased efficiency compared to the standard OFDM modem.
