Coherent query scheme for wireless backscatter communication systems with single tag
Hasanvand, Aminolah; Khaleghi, Ali; Balasingham, Ilangko (Journal article; Peer reviewed, 2018)An un-coded multi-transmitter query scheme is introduced for wireless backscatter communication systems in which M transmitters and N receivers are used for single-tag connectivity (M × 1 × N). The main idea is to harden ... -
Communication Aspects for a Measurement Based UWB in-Body to on-Body Channel
Floor, Pål Anders; Chavez-Santiago, Raul; Kim, Anna N.; Kansanen, Kimmo; Ramstad, Tor Audun; Balasingham, Ilangko (Journal article; Peer reviewed, 2019)A wireless capsule endoscopy (WCE) is a good option for the screening of the digestive system. To better facilitate detection of diseases at an early stage, gastroenterologists seek both higher frame rate and frame resolution ... -
