摘要

•The transmission design for an IRS-assisted MISO simultaneous SWIPT system is investigated.•For MISO systems, the transmission design for Gaussian signals and finite-alphabet signals can be unified into one optimization problem.•The optimization problems in perfect and imperfect CSI cases are investigated, respectively.•A PMO algorithm is developed to efficiently solve the non-convex problem with the requirements of phase shifts and energy harvesting.
