Method for determining direct current voltage breakdown in orthogonal frequency-division multiplexing transmission system, involves estimating frequency range by applying maximum likelihood estimation for direct current voltage breakdown

摘要

The method involves estimating a frequency range by applying a maximum likelihood estimation for a direct current voltage breakdown by loading of frequency-transformed orthogonal frequency-division multiplexing receiving symbols with corresponding matrix elements of pseudo inverses of a channel transmission matrix with channel transmission factors belonging to the transmission channels between each transmitting antenna and each receiving antenna. An independent claim is included for a device for determination of a direct current voltage breakdown in an orthogonal frequency-division multiplexing transmission system.
