OFDM
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

Tranfomasi-Fourier-dan-Wavelet
Tranformasi wavelet merupakan perbaikan dari transformasi Fourier.
Transformasi Fourier hanya dapat menangkap informasi apakahsuatu sinyal
memiliki frekuensi tertentu ataukah tidak, tapi tidak dapat menangkap dimana
frekuensi itu terjadi. Jika Transformasi Fourier hanya memberikan informasi
tentang frekuensisuatu sinyal, maka transformasi wavelet memberikan informasi
tentang kombinasi skala dan frekuensi
