The 'h' is the channel gain (which will be a complex number with magnitude between 0 and 1), and the "root p" is the square root of the transmit power.

Yeah, unfortunately you only have a 1/3 or 33.3% probability to NOT get the car. No one disputes the 1/3 or 33/3% probability TO get the car; it's the probability to NOT get the car that is in debate. TO get the car 1/3 Door A + 1/3 Door B + 1/3 Door C = 1 car to NOT get the car 1/3 Door B/C + 1/3 Door A/C + 1/3 Door A/B = 1 No car 1/3 car + 2/3 NO car = null equation Having 2 doors doesn't automatically mean 2/3 or 66% probability. They both combined to contain a total of 1/3 or 33.3% probability for you to NOT get the car. Your probability to pick one of those two doors is only 1/6 or 16.6%. And from a simple logic point of view, at no point in time do you have ANY probability to get Monty's no-car door. And where and when is that remaining 1/3 or 33.3% to NOT get the car if 2/3 or 66.6% of the time you don't get the car?! So 1/3 or 33.3% to get the car, and 1/6 or 16.6% + 1/6 or 16.6% to not get the car means the Monty Hall Problem is a 50/50 guess to either stay of switch. 🤙
@iain_explains 22 күн бұрын
Sorry, but you're clearly not understanding the game. Perhaps try watching the video again. If you get someone else to play the game show host, and try the game for yourself, you'll soon realise that if you change doors then you'll get the car 2 times out of every 3. Try it. You'll see.

@@iain_explains Iain - you seem like a decent fella and I certainly thank you for your time and reply. The ⅓-⅔ CULT claims that since you are picking from the ⅔ or 66.6% no car side, your chance to NOT get the car is twice the probability of you getting the car. Two is bigger than one so you are twice as likely to get the car if you would always switch. But at NO TIME do you have a chance to EVER pick 33.3% of that no car probability, Monty's door. Monty has that 33.3% no car probability. It is there before you even make the pick, yes I know that. But you have ZERO probability to get it. It can be in either of the no car doors and it still doesn't matter because you don't even have a 1% probability to pick it. Even though you are picking from the 66.6% side, you are only picking from 33.3%. So how does 33.3% car and 33.3% no car not a 50/50 guess? Then there are also these 100 door analogy, where if you pick one door and the host opens 98 doors to reveal no car, leaving only one no car door. And the claim is that wouldn't your car be more likely to be in the 99 doors that you didn't pick than the one you DID pick? Dude, you had ZERO probability to EVER pick those 98 no car doors, which means you have the 1/98 probability door you picked, and the 1/98 probability door that you didn't pick. You should always switch because you are now 99% more likely to have not picked the car?! You NEVER had access to the 98% the host opened. You have and always had access to only the 1% you picked, and the 1% you didn't pick. When this paradox first came about, these types of media platforms didn't exist to discuss it in. There were only biased media outlets promoting Vos Savant, leaving equal numbered of thousands, if not more, qualified mathematicians and university professors disagreeing. Now that we can clearly discuss it, my only purpose is to get it right. Thanks again, dude. No hard feelings. 🤙

Hello and thanks a lot for your amazing videos. I have a question, wasn't the first one at the receiver side a Matched Filter (instead of ZF)?
@iain_explains 26 күн бұрын
The equations in this video are for the baseband representation. There are many more details that would need to be added, if I were to include the full transmission chain, including pulse shaping filters, D-to-A converters, amplifiers, analog filters, ... etc. One of those things would also be a matched filter at the receiver - matched to the pulse shape. For more details on the baseband model, see: "How are Complex Baseband Digital Signals Transmitted?" kzfaq.info/get/bejne/ZtKbha2Y09_bm5s.html and "What is a Baseband Equivalent Signal in Communications?" kzfaq.info/get/bejne/m9qKdLWSsrSyYqc.html
