Journal ArticleDOI
Beam codebook based beamforming protocol for multi-Gbps millimeter-wave WPAN systems
Junyi Wang,Zhou Lan,Chang-Woo Pyo,Tuncer Baykas,Chin-Sean Sum,Mohammad Azizur Rahman,Jing Gao,Ryuhei Funada,Fumihide Kojima,Hiroshi Harada,Shuzo Kato +10 more
TL;DR: The proposed beamforming protocol employs discrete phase-shifters, which significantly simplifies the structure of DEVs as compared to the conventional BF with phase-and-amplitude adjustment, at the expense of a gain degradation of less than 1 dB.
Journal ArticleDOI
IEEE 802.15.3c: the first IEEE wireless standard for data rates over 1 Gb/s
Tuncer Baykas,Chin-Sean Sum,Zhou Lan,Junyi Wang,Mohammad Azizur Rahman,Hiroshi Harada,Shuzo Kato +6 more
TL;DR: The important features of IEEE 802.15.3c, the first wireless standard from IEEE in the 60-GHz (millimeter wave) band and its development, are explained.
Journal ArticleDOI
Single carrier transmission for multi-gigabit 60-GHz WPAN systems
Shuzo Kato,Hiroshi Harada,Ryuhei Funada,Tuncer Baykas,Chin-Sean Sum,Junyi Wang,Mohammad Azizur Rahman +6 more
TL;DR: The computer simulations have validated these new proposals for WPAN (wireless personal are network) design and significantly contributed a lot to global (IEEE802.15.3c) standardization which will be closed in the near future by issuing system specifications.
Journal ArticleDOI
Virtual time-slot allocation scheme for throughput enhancement in a millimeter-wave multi-Gbps WPAN system
Chin-Sean Sum,Zhou Lan,Ryuhei Funada,Junyi Wang,Tuncer Baykas,Mohammad Azizur Rahman,Hiroshi Harada +6 more
TL;DR: It is found that the VTSA scheme is capable of improving system throughput as much as 30% in both AWGN and multipath channels, and by coupling with higher-order modulation schemes, the system is able to achieve up to a maximum throughput of 3.8 Gbps.
Journal Article
Cognitive communication in TV white spaces: An overview of regulations, standards, and technology.
Chin-Sean Sum,Gabriel Porto Villardi,Mohammad Azizur Rahman,Tuncer Baykas,Ha Nguyen Tran,Zhou Lan,Chen Sun,Yohannes D. Alemseged,Junyi Wang,Chunyi Song,Chang Woo Pyo,Stanislav Filin,Hiroshi Harada +12 more
TL;DR: The latest developments in regulatory status and standardization initiatives in the field of TV white space cognitive communication systems are presented, with emphasis on required parameters as guiding references to corresponding system design.
