No computational hardness assumptions. There are different “flavors” of OFDM according what we put in the Prefix:. data. P. data. P. data. P. time. Prefix. Three main choices:. . CP-OFDM with Cyclic Prefix (CP). . ZP-OFDM with Zero Prefix (ZP). Division Multiplexing CO-OFDM. 1. Principle of orthogonal frequency-division multiplexing (OFDM). The principles of orthogonal frequency division multiplexing (OFDM) modulation have been in existence for several decades. However, in recent years these techniques have quickly moved out of textbooks and research laboratories and into practice in modern communications systems. The techniques are employed in data delivery systems over the phone line, digital radio and television, and wireless networking systems. Paul . pethsomvong. Zach . asal. Dr. in . soo. . ahn.
