Reducing error vector magnitude of OFDM signals using threshold vector circle method
SPIE Proceedings, 2016The main disadvantage of Orthogonal Frequency Division Multiplexing (OFDM) signal is the high peak-to-average power ratio (PAPR) which influences the system power efficiency and system performance in the presence of nonlinearities within the high power amplifier (HPA). The error vector magnitude (EVM) is one of the performance metrics by communications

Performance enhancement of a WCDMA/HSDPA+ receiver via minimizing error vector magnitude
2013 IEEE International Test Conference (ITC), 2013SNR enhancement of a 6-band WCDMA/ HSDPA+ directconversion transceiver supporting 21 Mbps High Speed Downlink Packet Access Evolved (HSDPA+) in a single CMOS die is evaluated in this paper. The paper mainly focuses on enhancing SNR performance of a WCDMA/HSDPA+ receiver by minimizing the error vector magnitude (EVM) with the digital compensations of ...

Error vector magnitude analysis for carrier aggregated OFDM signals with nonlinear HPA
2016 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS), 2016This paper analyses the impact on the error vector magnitude (EVM) of the received carrier aggregated orthogonal frequency division multiplexing (OFDM) signal when it is passed through a nonlinear high power amplifier (HPA). This analysis will help to measure the quality of transceivers in modern communication systems, which are highly sensitive to ...

Synthetic DSP approach for novel FPGA-based measurement of error vector magnitude
2010 IEEE International Test Conference, 2010A new implementation of EVM measurement has been developed in a production test environment using an FPGA-based DSP processor within an ATE test solution. The focus of interest is in identifying key areas of the DSP that affect measurement quality and optimizing their execution on an FPGA to increase measurement accuracy, precision, repeatability, and ...

Validation of Vector Magnitude Datasets: Effects of Random Component Errors
Journal of Atmospheric and Oceanic Technology, 1997Abstract A statistically consistent and physically realistic approach for validating vector magnitude measurements is developed, based on a model for random measurement noise that explicitly satisfies a nonnegativity constraint for all “noisy” vector magnitude measurements.
