General AltBOC Modulation with Adjustable Power Allocation Ratio for GNSS [PDF]
Journal of Navigation, 2015 Alternative Binary Offset Carrier (AltBOC) modulation signal has the constraint of an equal power allocation scheme. Thus, it is not flexible enough to meet different requirements. To solve this problem, we propose a General AltBOC (GAltBOC) modulation. The proposed technique can achieve the same function as AltBOC.

Generalized Discrete Fourier Transform for FBMC Peak to Average Power Ratio Reduction [PDF]
IEEE Access, 2019 Filter bank multicarrier (FBMC) is a strong candidate as a waveform based technique in advanced wireless communication systems (e.g. 5G), as an alternative to orthogonal frequency division multiplexing (OFDM). Like all multicarrier modulation techniques, FBMC suffers from high levels of a peak-to-average power ratio (PAPR).

On peak to average power ratio of generalized frequency division multiple access
IEICE Electronics Express, 2009 We propose a generalized frequency division multiple access (GFDMA) scheme which realizes a low PAPR characteristic compared with OFDMA, maintaining the sufficient capability of the frequency scheduling. GFDMA transmits the data with one or more frequency resources which can be divided into several pieces in the frequency domain.
