<p>Disclosed is a portable terminal possible to perform a predetermined interference avoiding operation for avoiding interference from other wireless communication systems, with more reliability. A portable terminal device (100) is provided with a wireless communication unit (116), which performs wireless communication via a base station (120) using a TDMA/TDD system; a frame-error monitoring unit (122), which monitors a presence or absence of the frame error in respective consecutive frames composed of a plurality of time slots; a storage unit (104), which stores the presence or absence frame errors as a frame error array; a calculation unit (126), which calculates a degree of similarity between the frame error array and each of delayed frame error arrays obtained by delaying the frame error array by every one frame; an determining unit (130), which determines whether periodic frame errors are present, based on the degree of similarity; and an interference avoiding unit (132), which performs a procedure for the periodic frame errors in a case where it is determined that the periodic frame errors are present.</p> |
