The PAPR Problem in OFDM Transmission: New Directions for a Long-Lasting Problem
Gerhard Wunder, Robert F. H. Fischer, Holger Boche +2
Peak power control for multicarrier communications has been a long-lasting problem in signal processing and communications. However, industry and academia are confronted with new c…
Construction of High-Rate Regular Quasi-Cyclic LDPC Codes Based on Cyclic Difference Families
Hosung Park, Seokbeom Hong, Jong-Seon No +1
For a high-rate case, it is difficult to randomly construct good low-density parity-check (LDPC) codes of short and moderate lengths because their Tanner graphs are prone to making…
Deterministic Selection of Phase Sequences in Low Complexity SLM Scheme
Jun-Young Woo, Hyun-Seung Joo, Kee-Hoon Kim +2
Selected mapping (SLM) is a suitable scheme, which can solve the peak-to-average power ratio (PAPR) problem. Recently, many researchers have concentrated on reducing the computatio…
Design of Multiple-Edge Protographs for QC LDPC Codes Avoiding Short Inevitable Cycles
Hosung Park, Seokbeom Hong, Jong-Seon No +1
There have been lots of efforts on the construction of quasi-cyclic (QC) low-density parity-check (LDPC) codes with large girth. However, most of them are focused on protographs wi…
Low-Complexity Demodulation for Interleaved OFDMA Downlink System Using Circular Convolution
Hyun-Seung Joo, Kee-Hoon Kim, Jong-Seon No +1
In this paper, a new low-complexity demodulation scheme is proposed for interleaved orthogonal frequency division multiple access (OFDMA) downlink system with N subcarriers and M u…
Adaptive Generation Method of OFDM Signals in SLM Schemes for Low-complexity
Kee-Hoon Kim, Hyun-Seung Joo, Jong-Seon No +1
There are many selected mapping (SLM) schemes to reduce the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) signals. Beginning with the conv…
On the Cross-Correlation of a -ary m-Sequence and its Decimated Sequences by
Sung-Tai Choi, Ji-Youp Kim, Jong-Seon No
In this paper, for an odd prime such that , odd , and with , the value distribution of the exponential sum is c…
Fast Correlation Computation Method for Matching Pursuit Algorithms in Compressed Sensing
Kee-Hoon Kim, Hosung Park, Seokbeom Hong +2
There have been many matching pursuit algorithms (MPAs) which handle the sparse signal recovery problem a.k.a. compressed sensing (CS). In the MPAs, the correlation computation ste…
A New Low-Complexity Selected Mapping Scheme Using Cyclic Shifted IFFT for PAPR Reduction in OFDM Systems
Kee-Hoon Kim, Hyun-Bae Jeon, Jong-Seon No +1
In this paper, a new peak-to-average power ratio (PAPR) reduction scheme for orthogonal frequency division multiplexing (OFDM) is proposed based on the selected mapping (SLM) schem…
New decoding scheme for LDPC codes based on simple product code structure
Beomkyu Shin, Seokbeom Hong, Hosung Park +2
In this paper, a new decoding scheme for low-density parity-check (LDPC) codes using the concept of simple product code structure is proposed based on combining two independently r…
