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. Why listening in large rooms is difficult..

Introduction (1). Optical coherent receivers operate on the principle of mixing an incoming optical field (information channel) with a high power local oscillator (LO) signal prior to detection by the photodetector. When the frequencies of the LO and incoming optical field carrier are the same, the baseband signal is directly extracted from the output of the photodetector (.
