Disclosed are a method and an apparatus for generating metadata of immersive media and disclosed also are an apparatus and a method for transmitting metadata related information. The apparatus includes: at least one of a camera module photographing or capturing the image; a gyro module sensing horizontality; a global positioning sensor (GPS) module calculating a position by receiving a satellite signal; and an audio module recording audio; and a network module receiving sensor effect information from a sensor aggregator through a wireless communication network; and an application generating metadata by performing timer-synchronization of an image photographed based on the camera module, a sensor effect collected by using the gyro module or the GPS module, or audio collected based on the audio module.

A frequency error estimator and an operating method of the frequency error estimator are provided. In the frequency error estimator and the operating method of the frequency error estimator, a frequency error between a transmitter and a receiver of a mobile communication system using a reference code is calculated, thereby improving the precision of estimation while reflecting variations in frequency over time.
