rtos pentium
Hi,
I have an old pentium laptop probably 133 Mhz with about 32 Megs of RAM. Is there any free RTOS that I can install on this system to play around with?
Thanks,

I am trying to check the roudtrip delay for 2 different QoS classes, UGS and BE. Intuitively, UGS should give less roundtrip delay than BE but I consistently see that its the other way around. Now I know that Ping uses TCP which may not be the best way to measure but still I would like to have...
solving fourier transform matlab
Your question should have been what is the purpose of FFT in general? Matlab is just a programming/testing environment for mathematical modelling so they provide FFT as a tool. What's important to know is that they use an algorithm called FFTW (Fastest Fourier...
unit impulse multiplication
I would like to differ here, if a sequence is written in its difference form then there is a one to one mapping between this difference equation and its z transform, z^-1 corresponds to a delay by one, if you extend it to the entire sequence then convolution does...
multiplication and convolution
I think you are completely confused .. there are continuous signals and discrete signals, then there are systems with finite or infinite impulse resonse. infinite impulse response does not mean infinite amplitude, it means that a certain system has an infinite...
this should be simple .... use the infinite cosine series formula in x, any engineering math book should have the formula, go upto 4th or 5th degree for sufficient precision.
convolution multiplication
multiplication is usual multiplication one constant times another, convolution is polynomial multiplication which is multiplying 2 polynomials.
Traditional communication systems like AM and FM were essentially single carrier systems because the information modulated just one carrier and was transmitted. There was just one oscilator which fed the carrier signal.
In multicarrier systems there are oscilator banks (eg. fdm very old way...
Re: Question:FFT in OFDM
-- you should actually try to understand the concept of guard period here. cyclic prefix guard period is needed to simplify the channel estimation process while providing temporal separation between the ofdm symbols to mitigate multipath interference.
the concept...
ofdm fading
You cannot use the Matlab conv here but if you really understand the convolution technique here's what you can do.
1. pre-pend and append n-1 zeros to your post-ifft ofdm signal. n = channel length
2. form an n-length vector from the zero-appended ofdm signal.
3. start a loop for m...
Hi guys,
I am stuck in an unusual situation. I have a belkin wireless router with a usb printer port and a usual cat5 cable coming from my office network. I want to setup a private wireless lan using the belkin router to setup some computers in such a way that only they have access to a printer...
Pointer issue
depends on the microcontroller .... if an address variable ie a pointer in your case has the same size as a long int or default int, you can do a typecast as shown in the previous post
Hi all,
I am not sure if Perl is included under PC programming languages section. Anyways I have a question regarding regular expressions. I have a file with SQL insert statements. Some of the statements have three commas in a row like ,,, and I want to use regular expressions to substitute...
