The Method of Conditional Expectations for Cubic Metric Reduction in OFDM
Saeed Afrasiabi-Gorgani, Gerhard Wunder
High variations in the OFDM signal envelope cause nonlinear distortion in the power amplifier of the transmitter, which is a major drawback. Peak-to-Average Power Ratio (PAPR) and…
An Introduction to OFDM-OQAM
Saeed Afrasiabi-Gorgani
The Filter Bank MultiCarrier (FBMC) modulation with Offset QAM (OQAM), also know as OFDM-OQAM, has been very well studied in, roughly speaking, the last 15 years. A rich literature…
Multicarrier PAPR Reduction by Iteratively Shifting and Concentrating the Probability Measure
Saeed Afrasiabi-Gorgani, Gerhard Wunder
The peak power problem in multicarrier waveforms is well-known and imposes substantial limitations on wireless communications. As the quest for investigation of enabling technologi…
Overshooting and -Norms of a Class of Nyquist Filters
Gerhard Wunder, Saeed Afrasiabi-Gorgani
To tightly control the signal envelope, estimating the peak regrowth between FFT samples is an important sub-problem in multicarrier communications. While the problem is well-inves…
