Peak to Average Power Ratio Reduction using a Hybrid of Bacterial Foraging and Modified Cuckoo Search Algorithm in MIMO-OFDM System
The Partial Transmit Sequence which reduces the PAPR (Peak-to-Average Power Ratio) in Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system using a novel optimization algorithm is proposed in this study. This novel optimization algorithm is based on a hybrid of Bacterial Foraging Optimization (BFO) and Modified Cuckoo Search algorithm (MCS) and is thus cal...
متن کاملSelective Tone Reservation method for PAPR reduction in SFBC-OFDM systems
The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems. The proposed algorithm is based on a time domain kernel which is added to the signal of the anten...
متن کاملPerformance Analysis of PAPR Reduction in MIMO OFDM System Using Modified Constant Modulus Algorithm
A rapid increase in the demand of high speed data communication access leads to the development of exciting technology named MIMO OFDM. MIMO OFDM technology is one of the 4G communication standards. Though it has many merits, it still suffers from high peak to average power ratio problem. Many techniques were introduced to solve this problem. This paper presents an excellent solution to tackle ...
متن کاملPeak to Average Power Ratio (papr) Reduction Techniques for Ofdm-mimo System
In the previous chapter, to get high data rate transmission, High Throughput techniques were analyzed for OFDM-MIMO System. OFDMMIMO systems based on OFDM symbols suffer from the problem of inherent Peak to Average Power Ratio (PAPR). The peak power of a multi carrier OFDM signal is a critical design factor for band limited communication systems, and it is necessary to reduce it as much as poss...
متن کاملPerformance Analysis of Mimo-ofdm Receiver Using Modified Pts Technique
Partial Transmit Sequence is one of the distortionless methods to reduce the peak-to-average power ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) systems. It is an attractive method since it provides PAPR reduction without any degradation in bit error rate (BER) performance. PTS has high computational complexity which increases exponentially with increase in subblocks. But mo...
