An Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information
Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...

متن کاملA PAPR Reduction Scheme Without Side Information For OFDM Signal Transmissions
Abstract—Orthogonal frequency division multiplexing (OFDM) is a promising broadband transmission technique. However, OFDM has a drawback of large peak-to-average power ratio (PAPR), which is proportional to the number of subcarriers. A PAPR reduction scheme called tone injection (TI) was proposed that exploits the property of a nonlinear modulo function. The TI is equivalent to the one that sup...
متن کاملObject Detection Scheme Using Cross Correlation and Affine Transformation Techniques
In object recognition, there are several situations which may cause object image detection failure including that the object zooming in, zooming out, rotated, mirror, or something deformation and the object sizes become irregular. In this paper, an object normalization technique used to make the object into standard, an affine transform technique make the same object to meet any irregular shape...
متن کاملSource Localisation Mapping using Weighted Interaural Cross-Correlation
Computational sound localisation using binaural microphones requires accurate Interaural Time Difference (ITD) estimation in order to infer an angle of incidence. The Phase Transform weighting function, used in generalized cross correlation calculations for microphone arrays is investigated here for application to ITD estimation in binaural head recordings. Empirical measurements using the meth...
