Hi. I'm a student learning wireless communication system.
I would like to know exactly why MMSE always shows better performance when comparing ZF and MMSE
in a MIMO system with a Rayleigh channel.
Thank you.

Hi, for the first question, I would like to know why the CN
group and Methyl group are both pointing out of the plane? How do I
look in order to be able to get the same answer? For the second
question, how do I know which one will point out of the plane and
which one will go into the plane?

Question about PageRank Hi ! I would like to know about PageRank information from a who has had expereience about it before, on following question: #What's the major limitation of PageRank? #Could you tell me how to compute the PageRank algorithm step-by-step? #What's the difference between PageRank and HITS? #What's the different computing PageRank into a huge webpage and a small webpage? I would like to know the performance

4. Wireless Communications: Background: Per recitation, a wireless communication signal traveling from a cellphone tower to your phone bounces off numerous obstacles, causing multiple copies of the transmitted signal with different delays to arrive at your phone. These copies can add constructively or destructively, resulting in an effect called "multipath fading". The simplest (and perhaps most common) model for such is Rayleigh fading, which is a consequence of the (celebrated) Central Limit Theorem that we will learn later in the...

There are two speakers at the front of the room. Each is outputting a 250Hz pure tone. For each of the following situations, will you hear constructive interference (a loud nolse) or destructive nterference (soft or no noise). A represents the wavelength of the 250Hz tone. You are 3A away from speaker A; 4A away...

Hi I just need to know if these statements are true or false and why!! 1. Electric field lines always point from higher to lower potential, meaning that a positive test charge would then seem to "fall" in the correct direction. 2. A student measures the potential between parallel plates A and B, and the meter reading is +30 V. The student concludes that there is a charge on plate B, but none on plate A. 3. If a capacitor...

I am comfortable with opening conversation and closing conversation. I think opening conversation is like greeting and shows your kindness. I always say hi to people I meet. When I meet friends and classmates in school, I always give them a big warm greeting. Then we start the conversation naturally. As for closing a conversation, it is quite easy. It is asked you to end the conversation with some specific words. That is.to.say you have to give signals to your...

hi, I would like help with corrections! I recieved my homework
back and the teacher circled 6.9 M ^-1 s^-1. How do you reach this
answer? How do I apply the formula for second order? : 1/[A] -
1/[A] = kt ( this was just what the formula in my textbook looked
like but I know when you google something there is slight variation
in each, and each person likes to write there formula a little
differently that helps them)...

1. Explain in your own words why regulation is important. I would like you to use 2 examples, one from human communities and one from the human body in your explanation. Make sure to include how regulation is enabled in each case (i.e. how is communication occurring?). I will give you an example, so that you know what I am looking for. When you drive a car and approach an intersection, you will receive a signal (communication) that tells you...
