Design of Transmitter and Receiver to Reduce ISI in Multi-Carrier CDMA System
In this paper we have consider a MC-CDMA where Inter-symbol interference is one of the biggest problem when the system is subjected in Awgn and Rayleigh Channel. Here we have considered the efficient Transmitter and Receiver to reduce the inter-symbol Interference without considering the use of equalizer. When the number of users gets large, each user tends to choose more than one carrier, whic...
متن کاملDifferent Techniques to Reduce the PAPR in OFDM System
Orthogonal Frequency Division Multiplexing (OFDM) is well known Technique for transmitting large data Over Radio waves. Its main disadvantage is PAPR (Peak to average power ratio) nothing but several sinusoidal leads. This paper presents Reduction PAPR using all proposed techniques . This Proposed techniques shows better performance for reduction in PAPR any technique can be used according to p...
متن کاملTo Study the Different Techniques to Reduce the PAPR in OFDM System
Orthogonal Frequency Division Multiplexing(OFDM) is a method in which modulation of signal is done. Orthogonal Frequency Division Multiplexing has become popular technique for transporting large amount of data in both wired and wireless communication. It is a digital modulation technique in which signal is transmitted in parallel mode. As compared to single carrier system OFDM is more unaffecte...
متن کاملVarious Techniques to Reduce PAPR in OFDM Systems: A Survey
A non-constant envelope with high peaks is a main disadvantage of Orthogonal Frequency Division Multiplexing (OFDM). These high peaks produce signal excursions into non-linear region of operation of the Power Amplifier (PA) at the transmitter, thereby leading to non-linear distortions and spectral spreading. Many Peak to Average Power Ration (PAPR) reductions methods have been proposed in the l...
متن کاملA Novel Approach to Reduce PAPR in OFDM Using combined DCT Precoding Technique and Clipping Method
One of the major drawbacks in Orthogonal Frequency Division multiplexing(OFDM) is high Peak to Average Ratio (PAPR).Reducing PAPR will not only reduces the complexity of Digital to Analog and Analog to Digital converters but also increases the efficiency of High Power Amplifiers (HPA). In this paper a combination of precoding technique (DCT) and clipping technique has been proposed for PAPR red...
