Wireless networks beyond 5G are expected to support a wide range of applications and use cases, and single-carrier (SC) based wireless technologies have been considered in the literature as a suitable solution for high-frequency bands and latency-critical applications. However, SC systems experience severe performance degradation under multipath wireless channels. In a realistic scenario, wireless channels can cause fractional delays that introduce devastating self-interference into the system. Therefore, in this paper, we present an extended channel model that considers pulse shaping and fractional delay. Moreover, we use the proposed model to analyze the performance of the SC transmission scheme with a root-raised-cosine (RRC) pulse shape over a fractional delay channel. In this context, we propose a flexible system design with the aid of the exhaustive search method to control the effect of self-interference on SC in the presence of a fractional delay wireless channel. Lastly, we provide bit error rate results (BER) to validate the accuracy of the proposed compensator for SC systems in practical scenarios.
