当发送信号通过非理想信道时,通常会产生码间干扰。采用均衡技术可以有效的进行补偿。均衡能够有效地克服传输中的多径干扰和消除码间串扰,是无线通信系统中的一项重要技术,并且在许多相关领域都有非常广泛的应用,目前已广泛用于通信、雷达、声纳、控制和生物医学工程等许多领域。介绍非线性均衡器,对非线性的判决反馈均衡和线性均衡做对比。仿真结果表明,判决反馈均衡器有着比线性均衡器更好的性能。
When transmitting signals through non-ideal channels, inter-symbol interference typically occurs. The use of equalization techniques can effectively compensate. Equalization can effectively overcome the transmission of multipath interference and eliminate intersymbol interference, is an important wireless communication system technology, and in many related fields have a very wide range of applications, has been widely used in communications, radar, sound Nanotechnology, control and biomedical engineering and many other fields. Introduce non-linear equalizer, compare the non-linear decision feedback equalization and linear equalization. The simulation results show that the decision feedback equalizer has better performance than the linear equalizer.
