ECE, P.D.A College of Engineing, Gulbarga Abstract: DVB-T uses vy popular multicarri modulation system such as OFDM and the OFDM signals in DVB-T has high Peak to Avage Pow Ratio (PAPR). One way to reduce the high PAPR is by using efficient techniques. In this research, we analyse the PAPR reduction of OFDM signals using SLM and PTS techniques. The input consided for DVB-T system is video signal taken from intnet. The simulations of these techniques are carried out using MATLAB. Keywords: OFDM, DVB-T, SLM, PTS, QAM, PAPR, Techniques I. INTRODUCTION Digital trestrial television (DTT) is also called as Digital Video Broadcasting-Trestrial (DVB- T) television is currently an efficient communication technology for broadcasting television (TV) signals[]. The European digital television ETSI EN 3 744, standard is DVB-T, for the trestrial transmission to fixed, portable, and mobile receivs[2]. The specification of framing structure, channel coding and modulation, for digital trestrial broadcasting is provided by DVB-T Standard. DVB-T system refs, to the source coding of data, audio signals and video signals, the channel coding and the technique for the transport of the DVB-T signals by means of all type of transmission media. In DVB-T, the OFDM is used to transmit 2k and 8k mode carris ov AWGN, Rician and Rayleigh Channel, the received signal at the receiv is corrupted. The corrupted received signal is manipulated in tms of SNR values (ranging from db to 6dB) and modulation techniques (4-QAM, 6-QAM 64-QAM and 28-QAM). OFDM modulation [3] is attractive technique for high data rate transmission, since it can cope with frequency selective fading channel. The Fig. gives the DVB-T System Physical Lay block diagram. In DVB-T the most sious problem of OFDM is high Peak to avage pow ratio (PAPR) which causes degradation of system pformance. So reduction of PAPR is vy much needed in ord to utilize the benefits of OFDM for DVB-T applications. Various PAPR reduction techniques are proposed in litature for OFDM system and in this research we have consided the most widely used techniques such SLM and PTS [4][5]. A. OFDM Model and PAPR Consid discrete time OFDM model having N subcarris then the discrete time OFDM signals is whe n = {,,...,N }. We will have x = {X}, whe X = [X(),...,X(N )] T, x = [x(),..., x(n )] T. Theoretically, the PAPR of OFDM signal is given as () (2) Whe E [ ] indicates the expectation opator, x(n) denotes the transmitted OFDM discrete signals which are obtained by applying (invse fast Fouri transform) opation on modulated input symbols X(k). 46
