However, the amount of feedback data increases with the number of users and the number of transmit antennas. In this paper, we propose a criterion based on the orthogonality between the users\u2019 channels to reduce this uplink load. Without cooperation between the users, we only allow users that are semi\u2010orthogonal to feed back their quantized channel information to the base station. We propose a lower bound on the sum rate for the proposed criterion. We show that the performance is almost independent of the number of quantized channel quality information and only channel direction information is important at the transmitter. Then, we consider a noisy feedback channel and propose an algorithm to reduce the noise effect on the analogue feedback.Copyright \u00a9 2012 John Wiley & Sons, Ltd.<\/jats:p>","DOI":"10.1002\/ett.2557","type":"journal-article","created":{"date-parts":[[2012,10,11]],"date-time":"2012-10-11T17:11:06Z","timestamp":1349975466000},"page":"809-819","source":"Crossref","is-referenced-by-count":2,"title":["Reduced feedback load using user selection algorithms for the multiuser multi\u2010input single\u2010output systems"],"prefix":"10.1002","volume":"24","author":[{"given":"Hajer","family":"Khanfir","sequence":"first","affiliation":[{"name":"Electronics and Communications Laboratory CNAM, 292 Rue Saint Martin 75141 Paris France"}]},{"given":"Didier Le","family":"Ruyet","sequence":"additional","affiliation":[{"name":"Electronics and Communications Laboratory CNAM, 292 Rue Saint Martin 75141 Paris France"}]},{"given":"Berna","family":"\u00d6zbek","sequence":"additional","affiliation":[{"name":"Electrical and Electronics Engineering Department Izmir Institute of Technology Urla 35430 Izmir Turkey"}]}],"member":"311","published-online":{"date-parts":[[2012,10,11]]},"reference":[{"key":"e_1_2_9_2_1","unstructured":"WeingartenH SteinbergY Shamai (Shitz)S.The capacity region of the Gaussian MIMO broadcast channel InCISS: Conference on Information Sciences and Systems Princeton N.J.
