Description
Summary:Abstract In this paper, two intelligent reflecting surface (IRS)‐assisted single‐input single‐output Golden codeword‐based modulation schemes for next‐generation networks are investigated. In Scheme 1, one pair of Golden codeword super‐symbols are transmitted over two consecutive time slots with the assistance of an IRS to maximise the received signal‐to‐noise ratio (SNR) in each slot. Scheme 2 applies component‐interleaving to the pair of Golden codeword super‐symbols and transmits the modified super‐symbols over four consecutive time slots with the assistance of an IRS to maximise the received SNR in each slot. A significant improvement in error performance is demonstrated over their counterparts, for both conventional/non‐access point (AP) or AP‐based IRSs. Scheme 2 exhibits superior error performance over Scheme 1, especially for small and medium IRSs. The theoretical average bit error probabilities for the proposed schemes are formulated and validated by simulation results. Low‐complexity detectors for the schemes under study are provided and the computational complexity imposed by these detectors are analysed and found to be extremely low.
