In this paper, a new channel information estimation scheme for multi-route multi-hop networks is discussed. Multi-hop network has received much attention recent years because of its large channel capacity. When the information bit streams are transmitted over multiple routes, a route diversity effect would also be possible. In order to improve the route diversity effect the receiver has to obtain...
As the diversification of the electromagnetic (EM) environment is spreading, it is essential to estimate the EM exposure in the mother's body and her fetus for pregnant women under various situations. This paper presents the development of the numerical model of a 7-month pregnant woman (composed of 56 organs, which includes inherent organs of pregnant woman) based on the high-resolution whole-body...
For reduction in bit errors on wireless channels, we proposed the multi-route coding scheme on multiple routes for wireless multi-hop networks. In this paper, we introduce ARQ to the multi-route coding. In the multi-route coding, the destination node combines and decodes sub packets which are encoded and divided by the source node. The intermediate node relays a sub packet, that is, only a part of...
In this paper, a novel peak-to-average power ratio (PAPR) reduction method named cyclic-shifted scramble code (CSSC) method is proposed for multicarrier CDMA (MC-CDMA) systems downlink. The proposed method utilizes the characteristics of multicarrier systems, i.e., if inverse fast Fourier transform (IFFT) input sequence changes, the output waveform also changes. In CSSC method, a scramble code assigned...
