Title:
カバレージ改善のための低PAPR変調
Document Type and Number:
Japanese Patent JP6438045
Kind Code:
B2
Abstract:
A method includes receiving a two-bit information stream comprising first and second bits and performing precoding using the two-bit information stream to determine multiple output signals. The precoding is performed to create a finite multiple of states for the output signals. The output signals comprise a first output signal based on a version of the first input bit and on a version of a second input bit, a second output signal based on a delayed version of the first input bit and the version of the second input bit, and a third output signal based on the version of first input bit and a delayed version of the second input bit. The method includes performing pulse shaping of each of the output signals to create pulse-shaped signals, combining the pulse-shaped signals to create a transmission waveform, and outputting the transmission waveform. Apparatus, computer programs, and computer program products are disclosed.
