| Abstract(in English) | Recently, interleaved frequency division multiple access (IFDMA) has been attracting attention as a multiple access scheme in the uplink of the future mobile communication systems because of its low peak-to-average power ratio (PAPR) property while obtaining the frequency diversity gain. However, since the signal received at the base station is time dispersive due to the asynchronous transmission among the simultaneous access users in the uplink, multi-access interference (MAI) occurs due to the distortion among the comb like spectrum and the bit error rate (BER) performance is severely degraded. In this paper, we evaluate the averaged BER performance of uplink IFDMA with an iterative interference canceller to remove the MAI in a frequency no-selective fading channel. Furthermore, we derive the conditional BER performance theoretically by introducing a coefficient which indicate the degree of residual MAI and evaluate the amount of MAI which can be removed by using the interference canceller. |
