Shielding effectiveness of thickness of various materials

Channel estimation techniques for OFDM systems based on a pilot arrangement are investigated. Channel estimation based on a comb type pilot arrangement is studied through different algorithms for both estimating the channel at pilot frequencies and interpolating the channel. Channel estimation at pilot frequencies is based on LS and LMS methods while channel interpolation is done using linear interpolation, second order interpolation, low-pass interpolation, spline cubic interpolation, and time domain interpolation. Time-domain interpolation is obtained by passing to the time domain by means of IDFT (inverse discrete Fourier transform), zero padding and going back to the frequency domain by DFT (discrete Fourier transform). In addition, channel estimation based on a block type pilot arrangement is performed by sending pilots in every sub-channel and using this estimation for a

用矩形窗设计线性相位FIR低通滤波器,给了源代码，已经调试过了。其中要用到一个函数myfreqz要自己编，在这也附上其代码。希望对大家有用。(Rectangular window with the design of linear phase FIR low-pass filter, to the source code, have been debug. To use a function which myfreqz to own, in that its code is also attached. Hope useful for everyone.)
