Assessment of Transient EMI Impact on LTE Communications Using EVM & PAPR
IEEE Access, 2020 The brief contact losses between the pantograph and the catenary in high-speed trains create transient interferences, which extend to the frequency bands used by telecommunication systems.

Simulation and Analysis of the Digital Transmitter EVM
工程科学与技术, 2009 :If the effects of the local oscillator (LO) phase noise and the power amplifier nonlinearity on the digital transmitter error vector magnitude (EVM) can be predicted easily and effectively, and the bit error rate (BER) can be predicted using the EVM, a ...

On the EVM computation of arbitrary clipped multi-carrier signals
EURASIP Journal on Advances in Signal Processing, 2011 A common figure of merit in multi-carrier systems is the error vector magnitude (EVM). A method for EVM computation of a multi-carrier signal without any underlying model (e.g., the Gaussianity assumption) was proposed in a previous work of the authors ...

On the Optimization of Iterative Clipping and Filtering for PAPR Reduction in OFDM Systems
IEEE Access, 2017 Orthogonal frequency division multiplexing (OFDM) offers spectral efficiency advantage, however, it is limited by peak-to-average power (PAPR) problem. The PAPR can be reduced using iterative clipping and filtering (ICF) scheme but requires that the same

Parallel PWMs Based Fully Digital Transmitter with Wide Carrier Frequency Range
The Scientific World Journal, 2013 The carrier-frequency (CF) and intermediate-frequency (IF) pulse-width modulators (PWMs) based on delay lines are proposed, where baseband signals are conveyed by both positions and pulse widths or densities of the carrier clock.
