When you do transmit filter, you must have already upsampled by 2 as you mentioned. When you downsample at receiver, there won't be aliasing hence.
When you say system, it includes both UE and Base station. I feel it is wrong to isolate one of them and call it a system. One of the main aspect of this system...
From what I know, the received signal in wireless system is y=hx + n. where n is complex gaussian white noise. After applying equalization, y* = y/h = x + n/h....
I think there are 2 ways to check if a system is LTI. First it has to be linear. There are 2 conditions for that -a) For 0 input, the output should be 0. b) If the...
There 3 Tx antennas, 2 Rx antennas. $$y = Hx+n $$. $$ \hat{x} = H^{-1}y $$ is how you equalize for H and decode x. As you can see, you have to apply pseudo inverse...
