COFDM Modulation Techniques for High-Data-Rate Wireless Communication
Orthogonal frequency-division multiplexing (OFDM) scheme 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 mapped onto a shared copyright frequency, allowing for efficient utilization of the allocated. COFDM, a variant of OFDM, further enhances performance by incorporating redundant prefixing to mitigate the influence of multipath fading.
