在OFDM系统中，宽带信道被分割相互重叠的窄带子信道，如果各子信道的带宽比信道的相干带宽要小，那么信号传输就有可能在无频率选择性衰落或者平坦衰落的信道进行。(In OFDM system The wideband channel is divided into narrowband sub-overlapping, if each sub- The bandwidth is less than the coherence bandwidth of the channel, the signal transmission is possible without Frequency selective fading or flat fading channels.)

The article concerns observing states of the Induction Motor (IM) using a Luenberger observer in the speed servo drive. The movement of the motor and observer roots is analyzed for a variable speed. Following the analysis, a new method for gain evaluation of the IM magnetic flux observer is presented. This structure is extended by including an adaptive speed observer. The functionality of the presented method is proved in simulations using MATLAB Simulink.
