I am now creating a simulink model of Wimax System. However, I have some trouble in the channel estimation block. I wanna compare the LMS and MMSE algorithm and wanna use the linear ,spline and cubic interpolation. Is the channel estimation part after the FFT part or after the ofdm de-assemble part? Could somebody send me the simulink block of channel eatimation part and the relative M file about the interpolation, LMS and MMSE algorithm. I am new to simulink and I am really need help. Thank you so much.

I' m using magic as layout editor with a scmos technology that is available when you install magic. I want to use irsim as switch level simulator for doing simple simulations of my circuits.

My question is this: Have i to build the spice models of the transistors simply putting into the standard spice models ( in spice3f for example ) the process parameters of the technology? , i must get on the web the spice models linked to...

Hello, I need to add a column to a matrix in Simulink. I have a matrix of 20x3 and I need to add another column with the values of a signal at certain moments of time, that is to say, in t=1s add the value to the first row (1,4 position), in t=1.5s to the second row (2,4 position), t=5s to third (3,4 position),� How I can do this?

Hi Matlab friends, I want to build a simple model within Simulink, but not finding the right block. I have three one-dimensional input signals called X, Y and Z. No I am interested in saving each value of Z in a 2D-lookup table. The values of X and Y should define the position where the Z-value will be stored within the lookup table. From my point of view an easy task - but I asked a lot of people and nobody could give me a solution. I also started playing with the adaptive lookup tables, but they seem to be not the right tool for that task. Is anybody out there who can help me? Would be gr...

According to a NY Times article, Bill Gates says that 5 percent of all Windows computers crash more than 2 times per day: [begin excerpt] "Mr. Gates acknowledged today that the company's error reporting service indicated that 5 percent of all Windows-based computers now crash more than twice each day." [end excerpt] This is very funny. Okay let's see how resident wintrolls like McCoy and Spalten spin this. Here are three suggestions: 1) Gates didn't really mean that. 2) The error-reporting service is wrong 3) The 5 percent were being used by OS/2 users who have u...

Hello, I have N signals on which I want to apply the same processing. If I use blocks allowing vector computation everything is OK. But How can I do with block not allowing vector computation (for example the "weighted moving average") ? I'd like the algorithm be independant of N, so copying the block N times is not a good solution (imagine if N is equal to 1000...). I tried using the "for iterator" block, but it doesn't seem it helps in this case. Is there a way to copy the block automatically ? Have you any other ideas ? Thanks Patrick Patrick Schoeneich wro...

We have a problem using IF in Simulink. We have a output (u) from 0-2000 and want to apply an IF-eq.: if (u<=100) u=u else u=100 S=F8ren wrote: > We have a problem using IF in Simulink.

Use a Saturation block with an upper limit of 100 and lower limit of 0. It's in Simulink -> Discontinuities. HTH, Ashish.

Model transformations represent the key for the the success of MDA, different approaches have been proposed and QVT is coming.

Hi, I've been interested in nlp and dialog agents for some time. I've been searching for some commercial apps that utilize a power of morphology analysis, syntax parsing etc. Although I found a little more than just simple regexp-based ALICE-like systems. So, maybe I missed something. Are there real-life examples of conversational agents or nlp-based dialog systems? I would appreciate if someone could advise me. I don't mean an all-knowing engine that talks like a human being. I mean a special-case application that provides nlp textual interface to solve concrete tasks...

Dear all, I have the layout of the RAM and I will be simulating the circuit by passing input vector stream to the RAM. I would like to know how can I estimate the power consumed by the RAM for each particular data in that vector stream (when I write into the RAM or read from RAM). Based on this I need to create a data dependent memory model (as a function of the zero/one-ratio of the input data). Thanks and Regards, Kamesh. Hi Kamesh, I do understand your need to create an accurate power library model for your SRAM. I feel it would be much easier to do it, if you have already created ...

How can I convert m-file which consist of ANN(Artificial Neural Network) to simulink block for simulation? Please do reply as soon as possible. Hi, you can use your m-file in Simulink with the user-defined functions. There is a Block matlab-fcn there.

Hi I have trouble with MSSQL2000 SP4 (without any hotfixes). During last two weeks it start works anormally. After last optimalization (about few months ago) it works good (fast, without blocks). Its buffer cache hit ratio was about 99.7-99.8. Last day it starts work slow, there was many blocks and dedlocks. There are no any queries, jobs and applications was added. Now buffer cache hit ratio oscilate about 95-98. I try update statistics and reindex some hard used tables, but there is no effect or effect is wery short (after few hours problem return). Mayby somene know what it could be? Is ...

Hello, I have a question about the archtest in proc autoreg. In the model part, we can test for the first order autocorrelation of residuals of regression model by Durbin-Watson test and by archtest we can test for the existence of conditional heteroscedasticity of error variances but is this for the errors of the regression or errors of the AR model for the residuals of regression fit? This kind of model should follow these steps: Regression model: y=b.x=e AR model for e: e(t)=d1.e(t-1)+...+dp.e(t-p)+a(t) ARCH (or GARCH) for a(t) square: So, when we write proc autoreg ...
