| Jul 22, 2021 at 13:10 | comment | added | Marcus Müller | I'd assume your book explains that! | |
| Jul 22, 2021 at 10:29 | comment | added | Shashank V M | @MarcusMüller that's a good question: How are the same signals combined in a fashion which increases the SNR? Unfortunately, I don't know the answer to this question yet. It might be a separate question. If it isn't, you are welcome to write a more complete answer. | |
| Jul 22, 2021 at 10:25 | comment | added | Marcus Müller | hmmmm OK, well, but then me welding next to your phone would also enable high data rate communications? | |
| Jul 22, 2021 at 10:24 | comment | added | Shashank V M | @MarcusMüller thanks for the clarification, I've edited my answer. The book does not say the data rate increases, rather it enables high data rate communication | |

| Jul 22, 2021 at 10:22 | comment | added | Marcus Müller | This answer goes a bit short - received power in itself does not increase your rate; it needs to be "useful"; and in that sense, you'd need to see the statement of the book in more context: Probably, before it says ".. a combiner in the receiver phase-accurately adds up the signal"; even without the phase correction, power might increase – but not the information rate. You hide that in the $\gamma$, which is fine, but really, you need to also look closely how you come from received power to SINR, because received power is S+I! | |
