摘要：To overcome the frequency-selective fading of high-frequency communications, this letter proposes a delay pre-compensation scheme for the intelligent reflecting surfaces (IRS)-aided wideband multi-user multiple-input single-output (MISO) systems, which can attain inter-symbol interference (ISI)-suppressed communication without relying on the typical channel equalization and multi-carrier modulation. Based on the obtained ISI-suppressed channel, a low-complexity delay based precoding algorithm is developed to minimize the transmit power of the base station (BS) by exploiting the successive convex approximation (SCA) framework, where the transmit and reflect precoding vectors are updated simultaneously at each iteration. The numerical simulations verify the effectiveness of our proposed scheme
