In this context, hybrid precoding (HP) is one of the most promising solutions, and it becomes utterly important in the case of the multi\u2010user scenario. In this paper, authors have analyzed the performance of the lattice reduction aided fully connected structured precoder for millimeter wave massive MIMO under multi\u2010user scenario. This paper deals with Korkine\u2013Zolotareff (KZ) and Lenstra\u2013Lenstra\u2013Lov\u00e1sz (LLL) algorithms for the lattice reduction (LR). And the presented results show the performance comparison between zero forcing (ZF), minimum mean squared error (MMSE)\u2010based linear precoder with LLL algorithm\u2010based reduction\u2010based ZF (LLR\u2010ZF), LLR\u2010MMSE, KZ\u2010ZF, KZ\u2010MMSE, and Kalman filter\u2010based precoder. Here, the performance of the precoders has been evaluated based on spectral efficiency, energy efficiency diversity order, and bit error rate. This work conveys some important findings: (i) effectiveness of the lattice reduction aided precoder in multi\u2010user scenario; (ii) numerical results pointed out that at low SNR condition, KZ\u2010aided MMSE hybrid precoder provides 4\u2010dB performance than a Kalman filter\u2010based precoder; (iii) KZ\u2010MMSE hybrid precoder outperforms the other precoder.<\/jats:p>","DOI":"10.1002\/dac.4853","type":"journal-article","created":{"date-parts":[[2021,5,6]],"date-time":"2021-05-06T19:37:56Z","timestamp":1620329876000},"update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Performance analysis of lattice reduction\u2010assisted precoder for multi\u2010user millimeter wave MIMO system"],"prefix":"10.1002","volume":"34","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-3409-5189","authenticated-orcid":false,"given":"Debdatta","family":"Kandar","sequence":"first","affiliation":[{"name":"Department of Information Technology North\u2010Eastern Hill University Shillong India"}]},{"ORCID":"http:\/\/orcid.org\/0000-0001-8184-0623","authenticated-orcid":false,"given":"Samarendra Nath","family":"Sur","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, Sikkim Manipal Institute of Technology Sikkim Manipal University Majitar India"}]},{"given":"Arun Kumar","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, Sikkim Manipal Institute of Technology Sikkim Manipal University Majitar India"}]},{"given":"Sukumar","family":"Nandi","sequence":"additional","affiliation":[{"name":"Department of Computer Science Indian Institute of Technology, Guwahati Guwahati India"}]}],"member":"311","published-online":{"date-parts":[[2021,5,5]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSTSP.2016.2523924"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2015.2455980"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1017\/9781316771655"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/COMST.2020.2971781"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11276-019-01976-x"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.12928\/telkomnika.v18i1.13674"},{"key":"e_1_2_8_8_1","doi-asserted-by":"crossref","unstructured":"AlkhateebA HeathRW LeusG.Achievable rates of multi\u2010user millimeter wave systems with hybrid precoding.
