Papr Reduction in Mimo Sc-fdma- a Survey
To meet the requirements of high data rate, third generation partnership project (3GPP) has come across the development of long term evolution (LTE). High data rate can be achieved with the help of an advanced modulation method. Orthogonal Frequency Division Multiple Access (OFDMA) was considered as a modulation method especially in the downlink of the communication systems. It gives many advan...
متن کاملReduction of PAPR for SC-FDMA System based on DCT and Hyperbolic Tangent Companding
SC-FDMA suffers from high Peak-to-Average Power Ratio (PAPR) problem, which restricts its usage in some applications. In this paper, a joint Discrete Cosine Transform (DCT) and hyperbolic tangent companding (HTC) technique has been studied in order to minimize the effects of the peak-to-average power ratio of the SCFDMA System. The proposed scheme utilizes a DCT rather than the conventional dis...
متن کاملTo analyze the power spectral density and PAPR of FDMA and SC-FDM
Abstract: Literature emphasizes the orthogonal frequency division multiplexing for high data rate transmission over wireless channels. This is most popular multi carrier communication technique. Due to its robustness against frequency selective fading channels, it copes with the problem of limiting bandwidth and power for transmitting higher data over wireless mobile systems [1]. However, it su...
متن کاملSC-FDMA based systems to Reduce PAPR by using a Modified Companding Scheme
The 3rd generation partnership project (3GPP) long term evolution (LTE) standard uses single carrier frequency division multiple access (SCFDMA), scheme for the uplink transmissions and orthogonal frequency division multiplexing access (OFDMA) in downlink. SCFDMA makes use of single carrier modulation and frequency domain equalization, it is a technique that has similar performance and essentia...
متن کاملA Low PAPR Visible Light Communication System Employing SC-FDMA Technique
White light emitting diode (WLED) technology has been regarded as an environment-friendly lighting in the future. The WLED lighting system is able to provide short range wireless communication while illuminating rooms. The WLED based visible light communication (VLC) systems employing orthogonal frequency division multiplexing access (OFDMA) technique has been investigated in many researches. H...
