This paper presents a physical and MAC layer analysis of the recently introduced IEEE 802.15.3c standard for multi Gbps communication at 60 GHz. We find the optimal beamwidth of the transmitting antenna, achieving a trade-off between the Piconet Coordinator discovery and the duration of the contention access period (CAP) of the IEEE 802.15.3c MAC superframe. To find the optimal beamwidth, we first...
In this paper we present preamble design for millimeter-wave single carrier wireless personal area networks. Several factors are considered for a successful preamble design, such as sequence complexity, operation range, associated delay, robustness to frequency offset. Complementary Golay sequences are selected, which combine flexibility and performance. Simulation results indicate at optimum threshold...
The paper presents a signal-to-noise ratio (SNR) mapping scheme for single-carrier (SC) frequency domain equalization (FDE) based millimeter-wave wireless personal area networks (WPANs). The effective SNR, defined as an average SNR over whole data frame after equalization, is a one-to-one mapper of the SNR in practical scenario in the sense of the same bit error rate (BER) performance. As the mapping...
Beam steering antenna is expected in 60 GHz wireless communication system to improve the signal to noise ratio and obtain high gain with wide cover range for high speed WPAN application. In this paper, patch antenna arrays with planar topology are investigated by synthesizing the network losses and devices such as phase shifters. The investigation results can provide a valuable guide line for the...
This paper investigates the adjacent channel interference (ACI) resistance of a multi-Gbps single carrier wireless personal area network (WPAN) operating in the 60 GHz millimeter-wave band. The significance of performance degradation due to ACI is investigated corresponding to varying factors such as types of modulation and radio frequency (RF) hardware impairments. The level of modulation scheme...
The paper presents a feasible frequency domain pre-equalization (pre-FDE) proposal in order to reduce the number of frequency domain equalizer (FDE) in a piconet. The pre- equalization scheme based on the cross-layer design on both physical layer and MAC layer is proposed and investigated in millimeter-wave 60-GHz wireless personal area networks (WPANs). The physical structure is designed so that...
The millimeter-wave 60-GHz wireless personal area network (WPAN) is being standardized by the IEEE 802.15 Alternative PHY Task Group 3c (IEEE 802.15.3c). The physical (PHY) layer design targets data rates of multi-giga bits per second (multi-Gbps). In this paper, two physical (PHY) layer designs based on single-carrier frequency-domain equalization (SC-FDE) and orthogonal frequency division multiplexing...
This paper describes R&D on millimeter wave systems under discussions and standardization activities at IEEE 8082.15.3c. The system is for WPAN (wireless PAN) supposed to transmit 2 Gbps (or higher) mandatory and 3 Gbps (or higher) optionally both at PHY-SAP (service access point). The subcommittee has been getting into final stage for standardization, and has voted for selecting 9 candidates...
