- clipping as a PAPR reduction technique
- License: Shareware
- Price:


The m-file investigates the effects of high power amplifier and the channel noise on the OFDM signal and then introduces clipping as a PAPR reduction method to reduce the HPA effect.

OFDM is considered the strongest candidate (if not the only) for the coming 4G technology, here i present a simulation that helps to fully understand the generation,transmission and reception of an ofdm signal, but without showing the channel noise or the HPA effects for simplification purpose.

the m-file helps you o understand the generatio,transmission and reception of an ofdm signal, and also shows the effect of the channel noise and the HPA on the ofdm signal.

- selective mapping as PAPR reduction technique
- License: Shareware
- Price:


we use (phase rotation)by multiplying all the subcarriers in the sum by different phases to create a new data vector, not only that but also as we don't know the optimum phases to give the best PAR we create more than one vector and then select the optimum.

3 days ago i've posted selective mapping method to reduce PAPR, but i used only 3 phase shifts (10,15 and 20) and that was to show the phase shift effect and how it changes the PAPR value, but now in that simulation i'm concerned more about choosing the optimum phase after trying all the possible phase shifts from 0:90 degrees, and then i've drawn a curve showing the PAPR of each phase shift, and showing the optimum phase shift.

if we have 16 subcarriers let us dedicate r1,r2,r3 and r4 as PRC or peak reduction carriers and transmit on x1:x12 so when x1:x12 summation creates a peak, a combination from r1,r2,r3 and r4 creates an anti peak but not the exact anti peak or the output would be a flat signal from which data can not be retrieved.
