The proposed SPS-SLM based OFDM system has shown better performance in reducing PAPR of OFDM signal and no need side information (SI) to recover original data at OFDM receiver.
An effective increase of attention in OFDM from optical communication community has recently observed.
Therefore, in this paper, Partial Transmit Sequences (PTS) method will be introduced, which divides the normal OFDM stream into several sub-streams and multiplying each sub-stream by different weights, then the optimum value will be selected to be transmitted with low PAPR [7].
However, for PTS, [W.sup.2] = [V.sup.P], V is the partition number of OFDM signal, and P=4 is the elements number of phase set [[phi].sup.([mu]).sub.i] = [0 [pi]/2 [pi] 3[pi]/2].

Since only simple linear computation is required, great promise in OFDM based VLC system has been shown.
OFDM radar has the following advantages [4]: flexible waveform design, using orthogonal subcarrier signal as subchannel which improves the utilization ratio of the spectrum, enhancing the ability of resisting the pulse noise and channel fading, with large time-bandwidth product, and easy to be processed digitally.
