In this article, we investigate the influence of sampling time offset on the bit error rate (BER) performance in interleaved frequency-division multiple-access (IFDMA) uplink systems. It is shown that even small sampling time offset results in inter-symbol interference (ISI) and in signal-to-noise ratio (SNR) degradation. To avoid this, a soft ISI suppression algorithm is proposed which allows to significantly improve the system performance. The proposed algorithm can be applied to both IFDMA
