Crowdsourcing systems often have crowd workers that perform unreliable work on the task they are assigned. In this paper, we propose the use of error-control codes and decoding algorithms to design crowdsourcing systems for reliable classification despite unreliable crowd workers. Coding theory based techniques also allow us to pose easy-to-answer binary questions to the crowd workers. We consider...
In order to improve the sensing accuracy of free spectrum in cognitive radio system, different sensing strategies were proposed according to the regions where cognitive users located: cognitive users located at the edge of the primary user's decoding region sense spectrum through part collaboration with its adjacent non-edge cognitive user; Cognitive users located at the non-edge region use multi-node...
