Orthogonal frequency division multiplexing (OFDM) is a promising modulation technique for transmitting large amounts of digital data through radio waves. One major drawback in OFDM communication is peak-to-average power ratio (PAPR). Mainly because of the nonlinearity of the high power amplifier, these results in high out-of-band radiation, inter-carrier interference, and bit error rate performance...
Peak-to-Average Power Ratio (PAPR) reduction is an attractive research topic among the OFDM transmission research communities. Partial Transmit Sequence (PTS) has been a promising candidate out of the proposed PAPR reduction techniques without any distortion. In any PTS system, partitioning of the OFDM frame into disjoint sub-blocks is a crucial step. Adjacent partitioning (AP) is a rather simple...
This paper proposes a new design for acquisition and broadcasting of images for motorway surveillance systems (MSSs). The new design enables the motorway users to access data of images taken by wireless cameras placed along the motorway. This has the potential to provide improved safety awareness by allowing the motorway users to know the actual or imminent traffic and road conditions. This paper...
