The power of each symbol within a codeword was controlled to reduce the codeword error rate (WER). Several RS-coded OFDM systems with power control are proposed. The WERs of the proposed systems as a function of the signal-to-noise ratio per bit were derived. We found that channel inversion at the transmitter in combination with the erasure generation by ordering fading amplitudes at the receiver provided the lowest WER among the considered systems. Furthermore, the erasure generation by ordering fading amplitudes was found to be better than the erasure generation by comparing fading amplitudes with a threshold.<\/jats:p>","DOI":"10.3390\/info14040247","type":"journal-article","created":{"date-parts":[[2023,4,20]],"date-time":"2023-04-20T05:35:46Z","timestamp":1681968946000},"page":"247","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Power Control of Reed\u2013Solomon-Coded OFDM Systems in Rayleigh Fading Channels"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7066-0555","authenticated-orcid":false,"given":"Younggil","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Electrical & Computer Engineering, University of Seoul, Seoul 02504, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"12","DOI":"10.1109\/26.554278","article-title":"Soft decision decoding of linear block codes based on ordered statistics for the Rayleigh fading channel with coherent detection","volume":"45","author":"Fossorier","year":"1997","journal-title":"IEEE Trans.
