講到多載波多傳送， 大家就會想到OFDM， 這是一項有很久歷史的技術，最近這項技術越來越受歡迎被用在無線通訊的運用上。
Multicarrier transmission, also known as orthogonal frequency division multiplexing(OFDM), is a technique with a long history that has recently seen rising popularity in wireless and wireline applications. One of the major drawbacks of multicarrier transmission is the high peak-to-average power ratio(PAPR) of the transmit signal.
We propose a concept to reduce the PAPR in OFDM systems by using the stadard arrays of linear block codes. Our scheme may be regarded as modified versions of the
selective mapping(SLM) and Partial Transmit Sequence(PTS), which are to reduce the PAPR by reducing code rate and selecting minimum PAPR from several coset leaders as the transmit signal. Because the coset leaders of a linear code are used for scrambling in our scheme, no side information is required to be transmitted and the
received signal can be easily decoded by syndrome decoding. Final our simulation results show that our scheme has good performance in PAPR reduction.
