1. A method for coding information for transmission in a wireless access network, the method comprising:
- providing a pool of sequences having a reduced peak-to-average power ratio;
mapping the information to a selected at least one of the sequences in the pool;
modulating the selected at least one sequence having mapped information; and
transmitting the modulated selected at least one sequence over an orthogonal frequency division multiple access (OFDMA)-based wireless link of the wireless access network.

Abstract
In a wireless access network, a transmitter provides a pool of sequences having a reduced peak-to-average power ratio. Information to be transmitted is mapped to a selected at least one of the pool of sequences. The selected at least one sequence is transmitted over an orthogonal frequency division multiple access (OFDMA)-based wireless link of the wireless access network.

7. A wireless transmitter for transmitting information over a wireless link, the transmitter comprising:
-
a sequence generator configured to generate a pool of sequences having a reduced peak-to-average power (PAPR) ratio; a sequence selector configured to map the information to a selected at least one of the sequences in the pool; a modulator configured to apply a modulation to the selected at least one sequence having mapped information; and a circuit to cause transmission of the modulated selected at least one sequence that represents the information over an orthogonal frequency division multiple access (OFDMA)-based wireless link. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A wireless receiver comprising:
-
correlation circuits configured to correlate an input signal received over an orthogonal frequency division multiple access (OFDMA)-based wireless link to respective ones of plural waveforms that are produced from application of difference cyclic phase shifts to a low peak-to-average power ratio sequence, the input signal including a modulated signal having information mapped to one of the plural waveforms; and a circuit configured to select one of the plural waveforms based on the correlations by the correlation circuits and to decode the selected waveform to information that was transmitted by a transmitter over the OFDMA-based wireless link. - View Dependent Claims (17)
