Reducing error vector magnitude of OFDM signals using threshold vector circle method

SPIE Proceedings, 2016
The 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

Validation of Vector Magnitude Datasets: Effects of Random Component Errors

Journal of Atmospheric and Oceanic Technology, 1997
Abstract 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.

ERROR VECTOR MAGNITUDE AND BIT ERROR RATE PERFORMANCE ANALYSIS IN THE B5G UPLINK CHANNEL

Fractals
This work evaluates the bit error rate (BER) and error vector magnitude (EVM) performance in the uplink channel of a 5G and B5G communication system. Singular value decomposition (SVD) and Moore–Penrose pseudoinverse (PINV) are used for user data encoding and decoding.
