PPT-Coherent Optical Orthogonal Frequency

Division Multiplexing COOFDM 1 Principle of orthogonal frequencydivision 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.

Describes the . transformation. (as opposed to evolution) of optical transport networks in response to an exponential growth in demand. At the end of yesterday, we addressed the case of using the dot product to determine the angles between vectors. Similar to equations from algebra, we can talk about relationship of vectors as well.
