A partial transmit sequence technique with error correction capability and low computation

International Journal of Communication Systems, 2013
SUMMARYOrthogonal frequency division multiplexing (OFDM) is a popular transmission technique in wireless communication. Although already widely addressed in many studies, OFDM still has flaws, one of which is the occurrence of high peak‐to‐average power ratio (PAPR) in the transmission signal. The partial transmit sequence (PTS) technique is one method

A Modified Partial Transmit Sequence Scheme for PAPR Reduction in OFDM System

2008 IEEE 68th Vehicular Technology Conference, 2008
Partial transmit sequence (PTS) is an attractive distortless peak-to-average power ratio (PAPR) reduction technique for orthogonal frequency division multiplexing (OFDM) system. However, the complexity of PTS increases exponentially with the number of sub-blocks as it requires an exhaustive searching over all phase factor combinations.

Partial transmit sequence-active interference cancellation for UWB OFDM transmission

2009 IEEE 20th International Symposium on Personal, Indoor and Mobile Radio Communications, 2009
A novel algorithm called partial transmit sequence-active interference cancellation (PTS-AIC) is proposed to implement interference avoidance functionality in an ultra-wideband (UWB) OFDM device. It can be considered as another application of the PTS algorithm that has been applied to an OFDM transmission to reduce its peak-to-average power ratio ...

An Improved Partial Transmit Sequence Scheme for PAPR Reduction in FBMC/OQAM Systems

2021 International Wireless Communications and Mobile Computing (IWCMC), 2021
The 5th generation mobile networks (5G) and their key technologies need to provide higher spectrum efficiency utilization and smooth integration of broadband and narrowband systems. Filter bank multi-carrier transmission with Offset Orthogonal Amplitude Modulation (FBMC-OQAM) has great advantages to achieve this goal by combating multipath effects and ...

Partial transmit sequence to improve OFDM using BFO & PSO algorithm

International Journal of Wavelets, Multiresolution and Information Processing, 2019
The Peak to Average Power Ratio (PAPR) in Orthogonal Frequency Division Multiplexing (OFDM) system can be decreased effectively through Partial Transmit Sequence (PTS) scheme. In optimum phase factors searches of the PTM scheme, there is a very high computational cost involved and this restricts its ability to be applied in practical applications ...

A novel two-layered suboptimal approach to partial transmit sequences

The 57th IEEE Semiannual Vehicular Technology Conference, 2003. VTC 2003-Spring., 2004
A high peak-to-average power ratio (PAPR) is a major shortcoming in multicarrier systems, as it causes non-linearity in the transmitter, degrading the performance of the system significantly. Partial transmit sequences (PTS) is one of the best methods in reducing PAPR, in which the information-bearing subcarriers are divided into M disjoint subblocks ...

Analysis of the Performance of Partial Transmit Sequences with Different Subblock Partitions

2006 International Conference on Communications, Circuits and Systems, 2006
This paper analyzes the performance of reducing the peak-to-average power ratio (PAPR) by partial transmit sequences (PTS) in OFDM system, and finds that it is dependent on the correlation of several candidate signals which is decided by subblock partitions and phase factors, while it is unconcerned with the input signal.

Reducing PAPR of OFDM signals using partial transmit sequences

9th Asia-Pacific Conference on Communications (IEEE Cat. No.03EX732), 2004
Orthogonal frequency division multiplexing (OFDM) is an appealing technique for achieving high-bit-rate data transmission, due to its robustness against the multipath fading and Intersymbol Interference (ISI). However, the occurrence of the potentially high peak-to-average power ratio (PAPR) restricts its application. Several methods have been proposed

A Novel PAPR Reduction Technique by Sampling Partial Transmit Sequences

2009 5th International Conference on Wireless Communications, Networking and Mobile Computing, 2009
Optimum partial transmit sequence method (OPTS), as one of the highest-performance PAPR reduction techniques, has very high computational complexity. Most sub-optimal schemes which are based on iterative PTS (IPTS), aim at balancing PAPR reduction performance and complexity by expanding the searching space of phase factor sequence with more iterative ...
