One of the major benefits provided by COFDM is in rendering radio broadcasts relatively immune to multipath distortion and signal fading due to atmospheric conditions or passing aircraft. Proponents of COFDM argue it resists multipath far better than 8VSB. Early 8VSB DTV (digital television) receivers often had difficulty receiving a signal.
Coded orthogonal frequency-division multiplexing (COFDM) is a telecommunications modulation scheme that divides a single digital signal across 1,000 or more signal carriers simultaneously. The signals are sent at right angles to each other -- hence, orthogonal -- so that they don't interfere with each other.

Technika OFDM jest prawie zawsze używana w połączeniu z kodowaniem kanałowym (COFDM, ang. coded OFDM), oraz przeplotem (ang. interleaving). Polega on na zamianie kolejności nadawanych bitów z pewnego fragmentu transmisji. Po odebraniu dane są odplatane i przywracana jest pierwotna kolejność.
Learn how COFDM, a form of digital modulation, copes with multipath and interference in terrestrial broadcasting. The article explains the key features of COFDM, such as orthogonality, guard interval, error coding, interleaving and CSI.
22 mar 2023 · COFDM (Coded Orthogonal Frequency Division Multiplexing) is a modulation scheme that divides data into small packets and transmits them on orthogonal subcarriers. It uses FEC coding to detect and correct errors and is suitable for various applications such as digital TV, Wi-Fi, and satellite communication.
This paper reviews the history, principles, performance and implementation of COFDM, a digital modulation technique for digital television broadcasting. It compares COFDM with other techniques such as VSB and QAM and discusses the challenges and opportunities of COFDM for terrestrial HDTV broadcasting.
