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…
