It plays an important role in reducing bit error rate and improving transmission efficiency over fading channels. In 5G NR (5th Generation New Radio) standards, LDPC (low-density parity-check) and polar channel codes are employed for data channels and control channels, respectively. If multiple interleavers are implemented separately for them, the cost increases significantly. To address this issue, a hardware multiplexing scheme for channel interleavers based on LDPC and polar codes is proposed in this paper. Firstly, the formulas for the processes of the control channel interleaving and data channel interleaving are derived with respect to 5G NR standard. Then, the hardware implementation structures of the two interleavers are given. Subsequently, hardware reuse is proposed by sharing the similar or identical parts between the two hardware structures. Simulation results verify the correctness of our proposed scheme and demonstrate that it can realize the hardware sharing of the two kinds of channel interleavers to reduce the cost of silicon.<\/jats:p>","DOI":"10.1155\/2021\/8872140","type":"journal-article","created":{"date-parts":[[2021,1,27]],"date-time":"2021-01-27T22:05:07Z","timestamp":1611785107000},"page":"1-13","source":"Crossref","is-referenced-by-count":11,"title":["Hardware Sharing for Channel Interleavers in 5G NR Standard"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4133-5494","authenticated-orcid":true,"given":"Xiaokang","family":"Xiong","sequence":"first","affiliation":[{"name":"School of Information and Communication Engineering and State Key Laboratory of Marine Resource Utilization in South China Sea, Hainan University, Haikou 570228, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9468-9061","authenticated-orcid":true,"given":"Yuhang","family":"Dai","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering and State Key Laboratory of Marine Resource Utilization in South China Sea, Hainan University, Haikou 570228, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6837-9024","authenticated-orcid":true,"given":"Zhuhua","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering and State Key Laboratory of Marine Resource Utilization in South China Sea, Hainan University, Haikou 570228, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5842-8171","authenticated-orcid":true,"given":"Kejia","family":"Huo","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering and State Key Laboratory of Marine Resource Utilization in South China Sea, Hainan University, Haikou 570228, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2506-5981","authenticated-orcid":true,"given":"Yong","family":"Bai","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering and State Key Laboratory of Marine Resource Utilization in South China Sea, Hainan University, Haikou 570228, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1846-7958","authenticated-orcid":true,"given":"Hui","family":"Li","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering and State Key Laboratory of Marine Resource Utilization in South China Sea, Hainan University, Haikou 570228, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4644-4892","authenticated-orcid":true,"given":"Dake","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering and State Key Laboratory of Marine Resource Utilization in South China Sea, Hainan University, Haikou 570228, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","volume-title":"Flexible Interleaving Sub\u2013systems for FEC in Baseband Processors","author":"R.
