{"Image DocumentName": "OFDMS/P. P/S. IFFT. FFT. Add CP. Remove CP. D/A. A/D. Multipath. Channel. \u2026", "Image ImageDescription": "OFDM is a multi-carrier modulation. Channel is divided into a number of orthogonal sub- channels. The high speed data signal is converted into parallel low speed sub-streams [3]. OFDM is effective against frequency selective fading and Inter Symbol Interference (ISI) [3]. Wireless data services are asymmetric, while using OFDM, the number of sub-channels can be adjusted flexibly to meet the different rate of downlink and uplink transmission [3]. OFDM can be jointly used with other access methods [6]. A major advantage of OFDM technology is that fast FFT/IFFT could be used for implementation [6].", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
