This paper presents performance analysis of Peak to Average Power Ratio (PAPR) Reduction techniques in Orthogonal Frequency Division Multiplexing (OFDM) System such as Clipping, Partial Transmit Sequence (PTS), Selective Mapping (SLM) and SLM with Clipping (Hybrid Scheme) .Complementary Cumulative Distribution Function (CCDF) is calculated for each technique with different number of sub carrier...

Orthogonal Frequency Division Multiplexing (OFDM) has been currently under intense research for broadband wireless transmission due to its robustness against multi-path fading. In multicarrier modulation, the most commonly used technique is OFDM, it has recently become very popular in wireless communication. The main drawback of OFDM is Peak to average power ratio (PAPR). This paper present sel...

Novel applications of online pH determinations at temperatures from -35 °C to 130 °C in technical and biological media, which are all but ideal aqueous solutions, require new approaches to pH monitoring. The glass electrode, introduced nearly hundred years ago, and chemical sensors based on field effect transistors (ISFET) show specific drawbacks with respect to handling and long-time stability...

This paper will report on long term behaviour of potential sensors used in cathodic protection steel reinforcement concrete. Cathodic (CP) systems, both impressed current CP (ICCP) and galvanic (GCP), need regular testing to establish the quality protection. In addition, ICCP may require adjustment output voltage or current. Various types have been relatively large numbers, comprised true refer...

OFDM Signal combines the multiple symbol representations method with a signal clipping method using a new hybrid PAPR reduction technique. The amplitude of the signal is limited to the threshold value using clipping method which considering the signal must be interpolated before A/D conversion and also different filtering technique has been proposed. The clipping technique has the subcarriers h...
