What is the most common way of extracting the flatband and threshold voltage of a MOS capacitor in Silvaco? (Either using the C-V measurement capability or not)
Can concurrent statements be synchronous?
I have a when-else statement like the following and I want to make it execute at the rising edge of the clock:
sig1 <= '1' when (sig2 = '1') else
'0'
can it be done without a process?
You're totally right about r and theta. I'm talking nonsense about that part. I don't know how I got this idea about real and complex part! They're sin/cosine representations, and I think they are behind the whole quadratute idea and how we can send two carriers simultaneously. I'm so new at...
Yes. Each symbol is a complex number which represents the waveform of your signal for that symbol. The real part is the amplitude and the imaginary part is the frequency (or phase).
In theory, we can describe the effects of the fading channel by first realizing that the latter is a...
You can visualize it by thinking about your receiver.
You probably already know that a wave has amplitude and phase components. You should also know that the multipath components of a fading channel are just waves that arrive at the receiver at different instants of time. This time shift is...
It seems that if you cheat a bit more you can get some results: I used the complex phase difference and complex phase shift blocks to inverse the phase rotation introduced by the rayleigh channel. Got results very close to theoretical.
Yes, this is exactly what I was thinking, because the Rx ISR that I mentioned transmits a response back (so it uses the Tx buffer). I guess it all comes down to how critical is what you're doing. If I try to add complexity I might end up blocking the program completely. On the other hand, you...
I'm sorry I wasn't clear enough. I was referring to the first character to be transmitted. I know that I am working on a non multi-tasking system, but something our professeur said baffled me: "You can't just ask for the buffer and then send because someone else might have taken it in the...
I decided to multiply all the complex paths together and then divide the signal (with AWGN added to it) by them. I'm not sure it works though because I get high error rates (0.5).
I am working on an Infineon board sending characters through the serial interface. Two interrupts are provided. One is raised just before the transmission of the last bit on the line and one just after that, when the Tx buffer is cleared. What is considered the best way to make the transmission...
How do I perform equalization before QPSK demodulation with a Rayleigh fading channel of more than one paths in simulink? (using the complex paths output of the Rayleigh block)
On an Infineon board (C167CS) I configure an output pin to be in open-drain mode and then I see with the oscilloscope that the output stays at 0V, whereas on a different pin, again in open drain, a LED attached to it switches on. Why don't I see any voltage change with the oscilloscope...
Thank you, that's what I was looking for.
And does anyone know why in the design of an antenna someone would choose to calculate only one and not the other. Could it be that the other is zero? Or there are cases where we are only concerned with one of them?
