COFDM Modulation Techniques for High-Data-Rate Wireless Communication

Orthogonal frequency-division multiplexing (OFDM) modulation is a widely adopted technique for high-data-rate wireless communication. It operates by splitting the transmitted signal into numerous copyright frequencies, each carrying data. These subcarriers are then modulated onto a shared copyright frequency, allowing for efficient utilization of the available. COFDM, a variant of OFDM, further enhances performance by incorporating cyclic prefixing to mitigate the impact of multipath fading.

The robustness of COFDM in combating multipath distortion makes it particularly suitable for wireless communication systems operating in environments with challenging channel conditions.
