以12脉波整流电路为研究对象，有效降低网侧电流的谐波畸变，其主要原因在于所采用的移相变压器，能过它可使各6脉波二极管整流器产生的低次谐波相互抵消。利用Matlab—Simulink建立模型对其进行仿真，并对其产生谐波电流进行分析和计算，阐述了其消谐原理。这种整流电路采用两个6脉波二极管整流器进行串联，功率因数较高，提高了直流电压的输出能力，对减少电网中的谐波干扰十分有效，可以有效地消除钢厂电力系统中较高次数的谐波。(Low-order harmonics with 12 pulse rectifier circuit for the study, effectively reducing line current harmonic distortion, mainly due to phase-shifting transformer used, it can make each six-pulse diode rectifier generated offset each other . Using Matlab-Simulink simulation modeling them, and analyze and calculate their produce harmonic currents, described its harmonic elimination principle. This rectifier circuit uses two 6-pulse rectifier diode in series, high power factor, increase the output capacity of the DC voltage to reduce power grid harmonic interference is very effective, steel power system can effectively eliminate high the number of harmonics. )

说明：  认知无线电技术的提出是为提高频谱利用率，而认知无线实现的关键技术是频谱感知，众所周知协作检测提高了衰落环境中认知用户系统检测的性能，该文章是基于协作检测提出新的检测方案，利用了双门限方法提高了系统性能，兼顾带宽有限和增强性能两个方面，是基于门限检测的协作检测性能优化的前提。对以后门限优化协作检测非常有用。(In this paper, we employ a double threshold method in energy detector to perform spectrum sensing, while a fusion center in the cognitive radio network collects the local decisions and observational values of the secondary users, and then makes the final decision to determine whether the primary user is absence or not. Simulation results will show that the spectrum sensing performance channels is improved significantly under the proposed scheme as opposed to the conventional method.)
