Talk:Near–far problem

Page contents not supported in other languages.
From Wikipedia, the free encyclopedia

This is as said just an analogy, in fact a human is very capable of filtering out loud sounds from other sounds, and sometimes the solution to not hearing your friend would be to actually turn up the stereo, results may vary.

Does this make any sense? --Tmegee 01:33, 1 July 2007 (UTC)[reply]

[edit]

I don't think of Near-Far as being related to SNR. When you add noise to a message, the receiver's rate of detecting the wrong symbol will increase. Near-Far comes into to play when a strong signal saturates the ADC (or other part of the signal chain). The information is not obscured by noise, but the receiver lacks the dynamic range to pull out the information. It is vaguely like SNR in that the receiver's AGC will cut back gain to prevent saturation causing the weak signal to fall into the "noise" (i.e. beyond the resolution of the ADC) of the ADC, but that's not the same thing as noise from one signal onto another. —Preceding unsigned comment added by Cgervasi (talkcontribs) 17:41, 14 May 2010 (UTC)[reply]

I just rewrote the article incorporating these points. IMHO it had to be re-written b/c near-far is not related to SNR. Maybe someone else can resurrect any good points from the previous revision that I failed to include. —Preceding unsigned comment added by Cgervasi (talkcontribs) 18:46, 14 May 2010 (UTC)[reply]
