Understanding DVB-T and its Reliance on COFDM Technology
DVB-T represents digital terrestrial television broadcasting standard. It enables the transmission of high-quality music and video signals over broadcast. A key component of DVB-T is its reliance on COFDM (Coded Orthogonal Frequency-Division Multiplexing) technology, which makes crucial role in ensuring robust and reliable reception.
COFDM divides the transmitted signal into numerous subcarriers, each carrying segment of the data. These subcarriers are then modulated at different frequencies, creating a advanced transmission structure that is highly resistant to interference and multipath fading. This makes DVB-T ideal for broadcasting in challenging environments where signal strength can fluctuate.
