An algorithm issue

Sat Jul 05, 2014 5:47 am

Basically calulating RQ receive quality is based on fixed window size of 4. The window will fill up by consecutive numbers, like 1,2,3,4 or 5,6,7,8, or 9,10,11, 12 but its 7, 9, 10, 12 then its no good. it's a moving window, if it receive 9, 10, 11, 12 then all the numbers before 9 discarded.

RQ=largest number which is 12 divide by window size which is 4 =3. the higher the RQ the better.

but if the window size becomes from 4 to 3 then RQ =4. but that's defeating the purpose. so, i don't understand this window size thing. common sense tells me sampling size or window size should d as large as possible for better result but the equation shows by shrinking the window size, RQ is actually higher, this doesn't make sense.

What's the context for this ? What is the signal being received and what is the noise (Gaussian,pulse ...) ?
