Abstract

A wireless transmission device () of the invention includes a VSWR measuring means () which measures VSWR; and a VSWR determining means () which determines reliability of a measurement value of the VSWR measured by the VSWR measuring means (). The VSWR determining means () includes a baseband signal analyzing means () which analyzes a baseband signal by detecting a difference between the baseband signal, and a delay signal of the baseband signal; a baseband signal density determining means () which determines a density of the baseband signal, based on the difference between the baseband signal and the delay signal analyzed by the baseband signal analyzing means (), and a VSWR output switching means () which restrains output of the VSWR measuring means, when the baseband signal density determining means () determines that the density of the baseband signal is low.
