In order to realize very high throughput wireless local area network (WLAN) systems, which demand multi Gbps capacities/bitrates, IEEE802.11ad (next generation WLAN standard in the 60GHz band) is in the standardization process. To evaluate the physical layer modulation and coding schemes in the standardization process, channel models in each specified environment are required. In this paper, propagation...
Wireless high definition video streaming is a typical application for millimeter-wave transmission. To achieve multi-gigabit transmission for multi video streaming, the system using dual polarized signal waves is a candidate to increase the throughput. In addition, beam-forming/steering is also suitable technology to obtain more high receiving power and avoid the shadowing disconnection by human mobility...
This paper proposes a spatial time-division multiple access (STDMA) throughput enhancement scheme for a multiGbps millimeter-wave (mmWave) wireless personal area network (WPAN) system. The system design includes in the medium access control (MAC) layer, an interference-monitoring mechanism and a heuristic TDMA time-slot scheduling engine, and in the physical (PHY) layer, a Reed-Solomon (RS) coded...
This paper investigates the impact of adjacent channel interference (ACI) and co-channel interference (CCI) on the error performance and throughput of a multi-Gbps millimeter-wave wireless personal area network (WPAN) system in both residential multipath line-of-sight (LOS) and non-LOS (NLOS) environment. It is found that the ACI that causes 0.5dB degradation in signal-to-noise ratio (SNR) for BPSK,...
Approximately double directional propagation measurement was performed for a millimeter wave WPAN. It was shown that even is a direct wave is not received, the delay spread can be made small (almost equal to the case of the direct component being received) if both the direction of the antenna and the antenna beam width are adjusted properly. In actual system designs, methods such as beam forming of...
Proposed PHY layer schemes are evaluated using the channel model that corresponds to each usage model in IEEE802.15.3c standardization process. NICT has contributed TSV model to the IEEE802.15.3c channel model subgroup. The model developed by NICT has been selected as the model for the evaluation of mandatory simulations. This paper describes the channel model for millimeter-wave band developed for...
