Re: how TWT work
A traveling wave tube (TWT) is an electronic device used to produce high-power radio frequency signals.
The device is an elongated vacuum tube with an electron gun (a heated cathode that emits electrons) at one end. A solenoid coil wrapped around the tube creates a magnetic...
I have 4 parameters for optimization.
3 of them are from the same nature,
and the fourth has different nature.
how can i manage this problem in MATLAB?
for instance, how can i change the forth every 4-5 generations?

The PCM Data Acquisition System is required to handle both analog and digital data. These data, acquired from the variety of sensors and transducers employed, are processed by the PCM system and recorded in digital form by an onboard magnetic tape recorder during flight...
In adition to last reply,
lower area is covered in 1800M frequency band rather than 900M.
In fact, every site(antenna) specializes 1800M band to more near
and non moving moblie stations.
Furthermore, the number of carriers in 1800M band is 374 and it is about
3 times the one in 900MHz (124...
