Dear Sir,
Can you please provide the code for An improved dft based channel estimation algorithm for mimo ofdm systems, as i have the code but the execution results are not related with the abstract results.
thanks in advance. ....etc

2-D DFT of two dimensional finite extent sequences.

2-D DFT and Convolution
The DFT can be computed with a fast algorithm and it is sometimes beneficial to do the convolution of two sequences A (M1 £ N1) and B (M2 £ N2) via point DFTs. Speed improvements are only possible if both sequences have large dimensions. Otherwise convolutions are better implemented via the convolution sum.

hello
i am a student in K.N.Toosi university of technology
during my project i found i wanna use circular gabor filter.
so i was wondering if you could give me your code ....etc

Procedure:-
1) Find the length of the first sequence x=x_length
2) Find the length of the first sequence h=h_length
3) Take the circular convolution order as N
4) If x_length < N, pad enough number of zeros to x, so that the number of samples in the modified x=N
5) If h_length < N ,pad enough number of zeros to h, so that the number of samples in the modified h=N
6) Take DFT for modified x=x(k)
7) Take DFT for modified h=H(k)
8) Compute Y(K)=X(K)*H(K)
9) Compute y(n)=IDFT(Y(k))
10) Verify if y=conv(x, ....etc

Procedure:-
1) Enter the number of points, N
2) Enter the input sequence elements, x
3) Create a vector for the sample index, ’n’
4) Initialize loop variable, ‘k’ for the DFT samples X(k)
5) Calculate the twiddle factor for each ‘k’
6) Multiply x and the twiddle factors , elements-by-element
7) Sum all the products, assign to X(k)
8) Plot the magnitude and phase spectrum
9) Verify the results with built in function

Abstract
Information hiding for covert communication is rapidlygaining momentum. With sophisticated techniques beingdeveloped in steganography, steganalysis needs to beuniversal. In this paper we propose Universal Steganalysisusing Histogram, Discrete Fourier Transform and SVM(SHDFT). The stego image has irregular statisticalcharacteristics as compare to cover image. Using Histogramand DFT, the statistical features are generated to train One-Class SVM to discriminate the cover and stego image.SHDFT algorithm is found to be efficient an ....etc
