Abstract
High Peak-to-Average Power Ratio (PAPR) of transmitted signal is one of the foremost problems to implement Orthogonal Frequency Division Multiplexing (OFDM) System. To transform the OFDM signal into anticipated statistics form that are identified by a linear piecewise function, the new Non-Linear Companding transform (NCT) set of rules is used. The variable slopes and inflexion points are introduced inside the probability density function (PDF) while the PAPR and Bit Error Rate (BER) are compared to achieve efficiency in the overall performance and flexibility in the Non-Linear Companding (NCL) form. The expected transform gain and signal attenuation factor and all the theoretical value study of this set of rules are given. The main parameters are evaluated specifically based on the selection criteria of the transform parameters focusing on robustness and execution aspects. The exploration is exactly proved in Simulink.
