COFDM Techniques for High-Speed Wireless Transmission
Orthogonal frequency-division multiplexing (OFDM) transmission is a widely implemented technique for high-data-rate wireless communication. It operates by dividing the transmitted signal into numerous channels, each carrying information. These subcarriers are then mapped onto a common copyright frequency, allowing for efficient utilization of the bandwidth spectrum. COFDM, a variant of OFDM, further enhances performance by incorporating circular prefixing to mitigate the influence of multipath fading.
The reliability of COFDM in combating multipath distortion makes it particularly appropriate for wireless communication systems operating in environments with complex channel conditions. Its ability to achieve high data rates, coupled with its resilience to fading, has made COFDM a prevailing choice for numerous wireless standards, including Wi-Fi and 4G LTE.
