In order to lower the car's weight, fuel consumption, this paper proposes an intra-car communications system in which the wire harness is replaced with the radio hoses. The proposed intra-car communications system uses a radio hose, a metalized flexible rubber hose that works as an oversized waveguide. The proposed system will provide much higher reliability than conventional wireless communications...
This paper proposes a new channel model for millimeter wave (60 GHz) for indoor applications, power amplifier and phase noise models at 60 GHz, an optimal global channelization over 9 GHz bandwidth, common mode signaling to bridge SC (single carrier) and OFDM (orthogonal frequency division multiplex) camps, and a robust payload as well as a header and preamble design for single carrier for practical...
The multi-Gbps wireless personal area network (WPAN) using 60-GHz is being standardized in the task group of IEEE 802.15.3c. In the physical (PHY) layer design, there are two competitive techniques, one is orthogonal frequency division multiplexing (OFDM) and the other is single-carrier frequency-domain equalization (SC-FDE), a.k.a., single-carrier block transmission (SCBT). This paper compared the...
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...
This paper proposes an air interface for ultra high-speed millimeter wave (60 GHz) systems which have been under standardization process at IEEE 802.15.3c: the proposed channel plan permits ease of portable device implementation employing the major crystal oscillator used in CDMA cellar phones. The proposed transmission modes offer much greater scalability, covering from several tens Mbps to over...
The paper proposed a multi-layer space-time block coded orthogonal frequency division multiplexing (multilayer STBC OFDM) scheme. It combines the spatial diversity and spatial multiplexing in order to exploit the benefits of both techniques. The transmit antennas are divided into several layers and each layer is encoded by STBC. The antennas transmit OFDM signals in order to deal with frequency-selective...
In the past years we have been focusing on developing DPC-OF/TDMA (dynamic parameter controlled orthogonal frequency and time division multiple access) system (Harada et al., 2003) which targets at beyond 100 Mbps data rate. In this paper, we extend DPC-OF/TDMA to support higher data rates with the same bandwidth of its original version. The evolved DPC-OF/TDMA is based on our newly proposed multi-layer...
