We define a parameter N which stands for the number of antennas used in a cell phone network.

After doing a research work, studies show that another parameter of the system which represents diversity order of the network, denoted by D,can be derived as below:

D = N+1.

The researcher writes about his conclusion as:

The diversity order of the cell phone network is limited to one plus the number of antennas.

Has the researcher written his conclusion correctly? Is it a proper written English?

If no, can you help him to improve his paper?!

Adding information due to the incisive comment from probablyme

He asked:

"Is N+1 a bound?"

The answer is yes, it expresses the upper band of the diversity order.

  • What is the unit on "performance"? – Azor Ahai -him- Jun 13 '16 at 20:51
  • Is quality measured in terms of "performance"? Is N+1 really a lower, upper, or other kind of limit of performance? – Em. Jun 13 '16 at 20:59
  • No actually, I assume that the units are appropriate. I just need to know if performance represents quality. Also, is N+1 a bound? If it is, then the word limited is ok. If N+1 is not a bound, then you cannot say that that the performance is "limited to". – Em. Jun 13 '16 at 21:07

Saying "limited to" suggest the diversity order can be anything less than the number of antennas up to and including A. If that is what you mean, then "limited" is okay. If it can only be exactly A, then you should use "equal to." Yes, that's what the equation says, but it's not necessary to be florid in this instance.

If the diversity order is exactly equal to A + 1, the only thing I would say is that it's stylistically better, better to say "plus one" after "antennas," because the number of antennas seems to be the real point, not the fact that they're added to one.

... equal to the number of antennas plus one.

  • I'm sorry, I'm not sure I understand why you want me to delete it? – Azor Ahai -him- Jun 13 '16 at 21:17
  • To clarify, before I edit, if someone asked you "What is the performance indicator for this network?" and the network had seven antennas, you would tell him "Eight."? – Azor Ahai -him- Jun 13 '16 at 21:20
  • Okay, so if you had a network with ten antennas, the diversity order could be anything from 0 to 11? – Azor Ahai -him- Jun 13 '16 at 21:24
  • Okay, thanks. In that case, I don't think it would be considered a "bound," though. – Azor Ahai -him- Jun 13 '16 at 21:25
  • Now, can I say sth limits the D to N+1 ? – Cardinal Jun 13 '16 at 21:40
