متن کاملPerformance Analysis of PAPR Reduction of OFDM Signal in Different Channels by Using Piecewise Linear Companding
In the OFDM communication system the main disadvantage factor is Peak Average to Power Ratio (PAPR) which limits the performance of the overall system. To limit this factor in the OFDM system there are so many techniques are there, depends on the nature of the system like clipping, Partial transmission, Selective mapping, Companding transform etc, in these technique companding technique is the ...
متن کاملPiecewise Linear Iterative Companding Transform for Papr Reduction in Mimo Ofdm Systems
This paper presents a effective iterative piecewise linear companding transform for PAPR reduction. It also presents an efficient iterative procedure of companding. This procedure mainly aims to mitigate the companding distortion that occurs during the clipping operation. This analysis provides a trade off between the reduction in PAPR and BER performance. Simulation results shows that proposed...
