—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)
