Selected mapping (SLM) is a well-known technique to reduce the peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM). SLM generally requires the side information for each OFDM symbol, which leads to decrease the transmitting efficiency. In addition, false side information detection degrades the bit error rate (BER)(More)
Crowdsensing has been widely investigated and its applications are being explored. We have used accelerometers embedded in the smartphone carried by bicycle users to detect road surface damages. However, detected damages locations are not aggregated and often, the same road surface damage can be detected several times at different locations due to(More)
To analyze the driving behavior is important for design a comfortable automatic driving. So far, conventional PID models was widely used to steer the vehicle. It had been assumed that the driver looks at the constant point in conventional PID model. However, all drivers have experiences that the gazing distance changes according to the situations. The PID(More)
