COFDM Modulation Techniques for High-Data-Rate Wireless Communication

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

The reliability of COFDM in combating multipath distortion makes it particularly suitable for wireless communication systems operating in environments with challenging channel conditions. Its ability to achieve high data rates, coupled with its resilience to fading, has made COFDM a popular choice for numerous wireless standards, including Wi-Fi and 4G LTE.
