The basic difference between OFDMA and SC-FDMA is that, there there is an additional block of N point DFT before the sub-channel mapping in SC-FDMA. This will effectively reduce the PAPR, thus the power amplifier will have a lesser linear range in SC-FDMA when compared with OFDMA
In modulation u r sending two signals but their frequencies are sum or difference of carrier frequency and signal frequency.In addition u send two signals at two different frequencies so more interference.
What is a linear factor What is a linear factor A linear factor is defined as a small change here will effect a small change there by a set value or factor.
1. Determine the height difference (a) between the start and end of the slope by subtracting the starting height from the final height (if it is a downhill slope the difference will be a negative number) 2. Determine the horizontal distance (b) between the starting point and the final point. If you only know the actual linear distance (c) along the slope, you can figure the horizontal distance using the Pythagorean Theorem: a2+b2=c2. For example, if the linear distance (c) along the slope from start to finish is 1000 feet, and the height difference (a) is 75 feet, then using the theorem you would have 752+b2=10002or 5625+b2=1000000. Your horizontal distance (b) would therefore be b2=994375 or b=997.2 feet 3. Divide the height difference (a) by the horizontal distance (b) and multiply by 100. This gives you the grade of the slope in percent. In the example it would be 75 ÷ 997.2 × 100 = 7.5% grade
A meter is a linear measurement, therefore 1 meter is the same as 1 linear meter.

distinguish between linear and non linear demands funcions

None. A linear inch IS an inch.
I have no idea. However, in theory there is a difference.
Nonlinear do not satisfy the superposition principle. Linear problems, as implied, do.
The spelling
its the same
You can measure things with a linear scale. Practically impossible with a non-linear scale.
A linear foot is 12 times greater than one linear inch.
a linear curve does not represent x^2
Linear is a straight line and non linear could be a curve or anything but a straight line
