On phase noise and it effect in OFDM communication system: Transcript
School of Electrical Engineering KTH To provide an overview of oscillor phase noise and its influence on OFDM systems Objective Over view of the phase noise phenomenon Ideal oscillator delivers a pure sinusoid. You can often stop noise that disturbs you without involving your council the police or the Environment Protection Authority EPA This brochure outlines steps you can take to prevent noise being an issue for you When noise annoys There are laws that 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. Nieman. †. , Marcel . Nassar. ‡. , Jing Lin. †. , and Brian L.
