| Abstract: | Interleaved frequency-division multiple-access(IFDMA) is investigated in 3GPP LTE and WINNER as a promising candidate for the uplink and for robust signaling. In addition to low peak-to-average power ratio(PAPR) of the transmit signal and low computational complexity for equalization and user separation, IFDMA provides an efficient implementation and good performance without channel knowledge at the transmitter. Its system model and characteristics are presented, and the application field is briefly introdu... |
