4. 3. When Handsets Became Smart

   University essay from Lunds universitet/Företagsekonomiska institutionen

   Author : Viktor Lundqvist; Erik Lundin; [2013]
   Keywords : Mobile industry; handset OEM; iPhone; Android; value migration; business innovation; disruptive innovation; Business and Economics;

   Abstract : The main cause of the intra industry value migration is that the base of competition has shifted from product performance to flexibility, differentiation and speed which in this industry means ecosystem, brand and time-to-market. The asymmetric business models and the two-sided platforms have proven to be a cause of inter industry value migration. READ MORE

5. 4. Low-PAR Precoding for Very-Large Multi-User MIMO Systems

   University essay from Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska högskolan

   Author : Christopher Mollén; [2013]
   Keywords : MIMO; PAR Reduction; Precoding; Multi-User; MIMO; toppvärdesreducering; förkodning; fleranvändarförkodning;

   Abstract : Storskaliga fleranvändar-MIMO-system, med hundratals basstationsantenner, studeras med allt större intresse både inom akademin och industrin. En anledning är att sådana system kan betjäna flera enantennsanvändare samtidigt över samma tids-frekvens-resurs med fleranvändarförkodning. READ MORE

6. 5. Comparing Dual Microphone System with Different Algorithms and Distances between Microphones

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Ariful Islam; Shafinaz Shahjahan Nitu; [2013]
   Keywords : Dual Microphone system DMS ; Babble noise; Adaptive filter; LMS; NLMS.;

   Abstract : Recovering a speech from a noisy environment is the most important work in communication system. The difficulty of this task increased when the signal is attenuated with a babble speech or cross-talk noise. When a mobile user talked in a public place e.g. READ MORE
