摘要
OFDM is an attractive technique for achieving high-bit-rate wireless data transmission. However, the potentially large peak-to-average power ratio (PAP) of a multicarrier signal has limited its application. Previously, we described a technique, based on partial transmit sequences, that provides improved PAP statistics with little loss in efficiency, and which is more easily implemented than the standard partial transmit sequence approach. One of the remaining challenges is how to transmit knowledge about the combining sequence to the receiver in a reliable fashion. Here, we describe a technique, using no overhead, for embedding this information within the transmitted data and reliably recovering it at the receiver.
