What is the basic difference between ofdma and sc-fdma?

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


What is the difference between the standard amplitude modulation linear addition and multiplication of signals?

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 what is the difference between a number line and a time line mathematically?

A number line represents real numbers arranged in a linear fashion, typically indicating their value and order, with equal spacing between points. In contrast, a timeline represents events in chronological order, illustrating the sequence and duration of occurrences over time, rather than numerical values. While both are linear representations, the number line focuses on quantitative relationships, whereas the timeline emphasizes temporal relationships.


How do you figure out the slope of grade in percent?

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
