Block interleaved frequency division multiple access for power efficiency, robustness, flexibility and scalability

• The multiple access solution in an IMT-Advanced mobile radio system has   to meet challenging requirements such as high throughput, low delays,   high flexibility, good robustness, low computational complexity, and a   high power efficiency, especially in the uplink. In this paper, a novel   multiple access scheme for uplinks denoted as B-IFDMA is presented. We   show that this scheme is able to provide equal or better error rate   performance than the Single-Carrier Frequency Division Multiple Access   (SCFDMA) schemes IFDMA and LFDMA, when considering realistic channel   estimation performance at the receiver and no reliable channel state   information at the transmitter. We also show that B-IFDMA provides   better amplifier efficiency than OFDMA and can provide better   end-to-end energy efficiency than IFDMA and LFDMA. Moreover, the scheme   shows a promisingly high robustness to frequency-offsets and Doppler   spread. Thus, this scheme can be regarded as a promising solution for   the uplink of future mobile radio systems.
