COFDM Modulation Techniques for Wireless Communications
Orthogonal Frequency Division Multiplexing OFDM is a prominent modulation technique widely employed in wireless communications systems. COFDM effectively transmits data by dividing the available bandwidth into numerous subcarriers that are modulated independently. These subcarriers are orthogonal to each other, ensuring minimal interference and enabling robust transmission over fading channels. A key advantage of COFDM lies in its ability to mitigate the effects of multipath propagation, a common challenge in wireless environments where signals travel along various paths with varying delays. By employing a cyclic/guard/pilot prefix at the beginning of each symbol, COFDM mitigates inter-symbol COFDM interference (ISI), which can distort received data.
