摘　　要：Turbo均衡技术将Turbo原理和均衡技术结合起来,通过对接收信号在均衡器和译码器之间迭代处理,提高系统抗符号间干扰(ISI)的能力。文中介绍了几种Turbo均衡技术,讨论了其计算复杂度,并给出了系统在Proakis信道下的误码性能。文中提出将应用于设计短波接收机。Turbo equalization technique combines the Turbo principle with equalization technology, the capability of canceling ISI is improved by iterative processing of the received signal between the equalizer and decoder. In this article several Turbo equalization algorithms are presented, and their complexities discussed and the simulation results under Proakis channels. The conclusion would be used to design the new HFreceiver.
