Abstract
Official abstract text for this publication.
A transmitter comprises a first peak-to-average-power ratio (PAPR) suppression circuit, a second peak-to-average-power ratio (PAPR) suppression circuit, and a first modulator. The first PAPR suppression circuit may receive a first sequence of time-domain symbols to be transmitted, alter the first sequence based on each of a plurality of symbol ordering and/or inversion descriptors to generate a corresponding plurality of second sequences of time-domain symbols, measure a PAPR corresponding to each of the second sequences, select one of the plurality of symbol ordering and/or inversion descriptors based on the measurement of PAPR, and convey the selected one of the symbol ordering and/or inversion descriptors to the second PAPR suppression circuit. The second PAPR suppression circuit may receive the first sequence of time-domain symbols to be transmitted, and alter the first sequence based on the selected one of the symbol ordering and/or inversion descriptors to generate a reordered and/or inverted symbol sequence.
First claim
Opening claim text (preview).
What is claimed is: 1. A system comprising: a first peak-to-average-power ratio (PAPR) suppression circuit, a second peak-to-average-power ratio (PAPR) suppression circuit, and a first modulator, wherein: said first PAPR suppression circuit is operable to: receive a first sequence of time-domain symbols to be transmitted; alter said first sequence based on each of a plurality of symbol ordering and/or inversion descriptors to generate a corresponding plurality of second sequen…
