COFDM Modulation Techniques for High-Data-Rate Wireless Communication
Orthogonal frequency-division multiplexing (OFDM) scheme is a widely implemented technique for high-data-rate wireless communication. It operates by dividing the transmitted signal into numerous subcarriers, each carrying information.
