reduction to papr in ofdm with Peak Windowing: The basic idea of peak windowing is to multiply the envelope of OFDM signal with a weighting function . Therefore, ~xE (t)= xE (t) f (t) where XE(t) =[x(t)] The weighting function given by: f (t)= 1-Σ α .w(t- t ) t-t w(t) : is the window function. t : denotes the position of a local maximum of the envelop xE(t) . α : attenuation constant . When the amplitude of envelop amplitude of the OFDM signal exceeds a threshold, a window function is applied to the envelop of the OFDM signal to eliminate the peak amplitude. windowing results in a smooth signal. Hanning window function will be used for w(t) As a matter of fact , other windows such as cosine, hamming and Kaiser may be employed.

对多功能动态试验装置的污垢厚度的检测，可以得到污垢形成的规律，从而有效地抑制污垢的形成。换热设备作为火电厂的重要设备之一，污垢的存在使传热能力下降，造成不必要的经济损失，通过对污垢的检测，掌握了热学法检测污垢的方法，提高换热设备的传热能力。(Dynamic tests on the multi-function devices detect the thickness of the dirt, the dirt can be formed by law, to effectively inhibit the formation of dirt. Heat exchanger equipment as one of the important thermal power plant, the presence of dirt reduced capacity to heat, causing unnecessary economic losses, through the dirt of detection, control the fouling thermal detection methods to improve heat transfer equipment heat capacity.)
