Hi, Wanna know how do you find the magnitude response of an FIR filter from the the pole-zero plot in the Z-plane...i know that at poles the magnitude is maximum and itz minimum at zeros...but how do you plot the response when there are a large number of poles and zeros.......

Hi, I am trying to simulate on Matlab a Rayleigh channel for my OFDM signal. I am using the code below to generate the channel coeficients. The output of this code is a matrix in this case: h = (modified_jakes1(100,2000,10,3,100,0)) is 100 coefficients and 3 multipath chanel.(is this correct?) how can i filter my time domain signal with these coefficient? any idea how to equilize the...

Dear Friends, I have read in DSP books that the HILBERT transform of "a*cos(wt)" is a sine with the same amplitude and frequency,means: a*sin(wt). In MATLAB, I have tested this problem in a m_file : with "FIlter Design Toolbox" I have designed a hilbert transform

Hi All, I am new to this group, I am working on Graphic Equalizer for octave 1 with biquad IIR filters. I had implemented this one in cascade form and now trying to implement same in parallel form. First of all I calculate the single equivalent Transfer Funtion from several cascaded biquad filter and then using residuez of matlab (which is based on partial fraction expansion) try to realize the f...

At the moment I am working on my thesis on "fault detection in pumps using vibratory signal analysis". This is to be done by comparing two groups of the signals, one for normal state of the machine and another attributed to its faulty conditions (in which a specific fault is artificially imposed to the system under the same working conditions as of the normal state). My problem is a high-amplitud...

hello if anyone can help me in specify image bands using matlab, plzzz replay as soon as possible this is my image registration algorithm in which step 8 is related to image band 1. Apply FFT to images I1 and I2 ? F1(x, h) and F2(x, h); 2. Compute the absolute values of F1(x, h) and F2(x, h); 3. Apply a high pass filter to the absolute values to remove low freque...

It's perhaps a silly question, but I don't see what I'm doing wrong. I'm trying to calculate the FT of a signal containing only dirac impulses. To avoid aliasing I first low pass the signal with a Butterworth filter (should I take another one?) and than use the matlab function "fft" to transform the signal. Here an example: %The signal with two pulses: x=[zeros(1,1000) 1 zeros(1,800) 1 zeros(1...

Can somebody please point me to a published paper or a book where they discuss on how to readily code or implement a real time recurrent neural network algorithm. It could be using gradient decent or discrete extended kalman filter. I need to use this for a signal estimation problem. My RTRL has one input (the input to estimate) which varies at random and one output. Please do not direct me toward...

Hi all, I am modelling a multipath rayleigh channel using matlab function Rayleighchan. This function models the channel as a FIR filter. You can find the algorithm in the matlab help rayleighchan page or look at the document attached. Can anybody help me understand the algorithm? why is the channel modelled as a sum of sinc? Best Regards, Thouraya

Hi All, I have to make a deblocking filter in matlab for MPEG-4 video. For it I take frames from the video and and using in matlab. the frame size is 144x176.My first step is to find the activity across the 8x8 boundary blocks in the image. and then classify the block as smooth,complex region. for that I first convert image into gray and then taking the 8x8 blocks, then on blocks i apply my fo...

Hello everyone. I recently joined this group. I'm a PhD student pursuing equalization. I'm interested in TEQ(shortening filter) and FEQ ( freq domain equalization). But to me, it seems that these two have been studied mostly in the context of DMT(DSL). Literature does say that in DSL, delay spread can be up to 100 symbols, thus TEQ and/or FEQ may be needed. But now, in wireless, OFD...

Dear all, I am trying to generate a noise channel for a synchronous downlink MC-CDMA through a zero-mean complex Gaussian process through a designed filter whose power spectrum density (PSD) is shaped as classic Doppler PSD. The symbol rate, Rs, which is the chip rate over N subcarriers is set to 3.84Mchip/s.? I have considered a normalized Doppler frequency of fdT = 0.001 where T is the durat...

Hello everybody, I have a ".m" & ".mdl" file in MATLAB that uses filter design toolbox to create fir interpolation, decimation & multirate filters. Is there any method/tool/program that can generate the exact equivalent C/c++ code that performs the same function as the corresponding ".m" & ".mdl" was doing? All type of replies a
