IFDMA - A Promising Multiple Access Scheme for Future Mobile Radio Systems R. Pon arun kumar. Abstract The Interleaved Frequency Division Multiple Access (IFDMA) scheme is based on compression‚ repetition and subsequent user dependent frequency shift of a modulated signal. IFDMA is a promising candidate MA scheme for non adaptive transmission in the uplink of future mobile radio systems.

device which receives the radio waves and converts them into usable form of waves. The antenna is used for receiving the radio waves (electromagnetic waves) and converts them to alternating currents and give to the receiver‚ and the receiver extracts the desired information. The electronic filters in the receiver is used to separate the desired radio frequency signal from all the other signals picked up by the antenna‚ an electronic amplifier is used to increase the power of the signal‚ and finally recovers
