The advancements in telecommunication technologies require an efficient FFT\/IFFT processing device to meet the necessary specifications which depend on the particular application. A real-time implementation of high-speed FFT\/IFFT processor with less area that operates in minimal power consumption is essential in designing an OFDM integrated chip. A comparative study of efficient algorithms and architectures for FFT chip design is presented in this paper. It is also recommended that mixed-radix\/higher-radix algorithm combined with Single-path Delay Commutator (SDC) architecture is appropriate for massive MIMO in 5G, optical OFDM, cooperative MIMO and multi-user MIMO-based applications. <\/jats:p>","DOI":"10.1142\/s0218126618300015","type":"journal-article","created":{"date-parts":[[2017,7,6]],"date-time":"2017-07-06T23:08:08Z","timestamp":1499382488000},"page":"1830001","source":"Crossref","is-referenced-by-count":23,"title":["A Survey on FFT\/IFFT Processors for Next Generation Telecommunication Systems"],"prefix":"10.1142","volume":"27","author":[{"given":"Elango","family":"Konguvel","sequence":"first","affiliation":[{"name":"Department of Electronics Engineering, Madras Institute of Technology Campus, Anna University, Chennai, Tamilnadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muniandi","family":"Kannan","sequence":"additional","affiliation":[{"name":"Department of Electronics Engineering, Madras Institute of Technology Campus, Anna University, Chennai, Tamilnadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2017,10,30]]},"reference":[{"key":"S0218126618300015BIB004","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2002.802566"},{"key":"S0218126618300015BIB005","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9780511841224"},{"key":"S0218126618300015BIB009","volume-title":"Digital Signal Processing Principles, Algorithms and Applications","author":"Proakis J.
