Hey there..
I'm looking for Reference Books to study MATLAB code for Dynamic Channel Assignment in cognitive radio network..
Could u guys please suggest to me good books for me to refer to..
Thanks in advance.. =)
Hey there..
I'm trying to set up a cognitive radio network for mobile system which will make use of the available spectrum of TV white space (UHF) using Dynamic Channel Assignment to distribute the the users to the available channel..
What should i consider to set up this kind of network...
Let say the circular convolution of two discrete-time signals x1[n] and x2[n] produces yet another discrete-time signal y[n] of the same length.
How am I going to recover x2[n] from knowing x1[n] and y[n]?
Thank you.
hey there..
I really hope u guys can help me extracting the important element from the question below;
A signal is sampled at the sampling rate of 10kHz. The signal has useful signal content
between 1kHz and 2.4kHz, and distortion of not more than 1dB is required for this range. It
is known...
Hey there.. I'm having problem on obtaining unit ramp input response.
I've got no problem to find unit step response..
BUT, to find unit ramp response, i need unit ramp input response..
that's my problem..
should i use lsim function to get it?
U can see the question in the attachment..
Hey there.. I've got couple of questions need to be answer.. i really got no idea to solve it..
1) During DC biasing measurement, if CE changes from 0.1 µF to 1 µF, what happen to the readings in VE (assume CE is ideal capacitor, no parasitic resistance or inductance)?
2) The input and output...
Find the output to each of the inputs given below. For which cases is the transmission
distortionless? For the other cases, indicate what type of distorsion in imposed.
(a) cos(48πt) + 5 cos(126πt)
(b) cos(126πt) + 0.5 cos(170πt)
(c) cos(126πt) + 3 cos(144πt)
(d) cos(10πt) + 4cos(50πt)
Solution...
Hey there.. got question here..
i been searching around the net.. but still didn't get any answer for my question..
An analogue source produces an audio and video signals. Explain with a transmitter block diagram, how the two signals can be transmitted with other digital signals over a noisy...
Explain the advantages of Double minimum Method over SWR Meter in terms of SWR measurement.
I just got one advantage..
for double minimum method, we can measure high and low SWR compared to SWR meter that can only measure low SWR.
i just don't know, if there's any other advantages..:sad:
has a transfer characteristic |H(f) given in the link below. The transmission is at maximum error-free rate of 4,800 bps. Compute the SNR (signal-to-noise-ratio) at the channel output. Does the output signal suffer from any distortion?
