First, we derive expressions for the probabilities of false\u2010alarm and signal detection for an optimal detector in the considered MIMO\u2010NOMA CR setup. Next, we study a constrained optimization problem that maximizes the sum rates of CCS and SSR schemes, with a constraint on the power allocation at SUs. This problem is shown to be a constrained convex optimization problem. Later, we analytically characterize and compare the sum rate performances of CCS and SSR schemes in MIMO\u2010NOMA CR and MIMO\u2010based orthogonal multiple access (MIMO\u2010OMA) CR networks. Extensive computer simulation results are presented which corroborate our analysis, which also quantifies the gain in performance of the proposed MIMO\u2010NOMA CR network employing SSR scheme when compared to conventional MIMO\u2010OMA CR systems. Furthermore, we present an experimental study based on RTL\u2010SDR setup, which supports our theory and also paves way towards a practical implementation of the proposed framework.<\/jats:p>","DOI":"10.1002\/ett.4602","type":"journal-article","created":{"date-parts":[[2022,7,18]],"date-time":"2022-07-18T04:50:10Z","timestamp":1658119810000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Non\u2010orthogonal multiple access\u2010aided MIMO cognitive radio networks with selective reporting"],"prefix":"10.1002","volume":"33","author":[{"given":"Tamanna","family":"Yasrab","sequence":"first","affiliation":[{"name":"PES Centre for Intelligent Systems PES University Bengaluru India"}]},{"given":"Rajalekshmi","family":"Kishore","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering The National Institute of Engineering Mysore India"}]},{"given":"Sanjeev","family":"Gurugopinath","sequence":"additional","affiliation":[{"name":"PES Centre for Intelligent Systems PES University Bengaluru India"},{"name":"Department of Electronics and Communication Engineering PES University Bengaluru India"}]}],"member":"311","published-online":{"date-parts":[[2022,7,17]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"crossref","unstructured":"YasrabT GurugopinathS.Spectral efficiency of MIMO\u2010NOMA cognitive radios with energy\u2010based spectrum sensing.
