1. 1. Efficient Transmission over Unknown Channels

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Ranjitha Gubbi Suresh; [2020]
   Keywords : Multi-Layer Transmission; RBIR; HARQ; mixing layers; successive demodulation; Wi-Fi; Technology and Engineering;

   Abstract : In recent years, digital transmission techniques have been continuously evolving by employing increasingly more advanced Modulation and Coding Scheme (MCS). However, when the wireless channel is varying rapidly, it is hard or even impossible for the transmitter to select the proper MCS. READ MORE

3. 2. On Forward Error Correction in IEEE 802.15.4 Wireless Sensor Networks

   University essay from Institutionen för informationsteknologi och medier

   Author : Wei Li; Zhiyuan Guo; [2012]
   Keywords : IEEE 802.15.4 standard; WSN; FEC; HARQ; reliability; energy efficiency;

   Abstract : Wireless Sensor Networks (WSN) are used in many applications, for example industrial applications, automatic control applications, monitoring applications, to name but a few. Although WSN can employ different standards in order to achieve short range wireless communication, the mainstream of the market is toadopt the low-power, low-rate IEEE 802. READ MORE

5. 4. Turbo Equalization for HSPA

   University essay from Kommunikationssystem

   Author : Cagatay Konuskan; [2010]
   Keywords : Turbo equalization; MMSE; HSPA; ISI; decoding; equalization; low complexity; HARQ;

   Abstract : New high quality mobile telecommunication services are offered everyday and the demand for higher data rates is continuously increasing. To maximize the uplink throughput in HSPA when transmission is propagated through a dispersive channel causing self-interference, equalizers are used. READ MORE

6. 5. Performance Evaluation of TCP Variants over UMTS Networks

   University essay from Institutionen för informationsteknologi

   Author : Nikunj Modi; [2008]
   Keywords : ;

   Abstract : With the evolution of 3G technologies like Universal Mobile TelecommunicationSystem (UMTS), the usage of TCP has become more popular for a reliable end-to-end (e2e) data delivery. However, TCP was initially designed for wired networks and therefore it suffers performance degradation due to the radio signal getting affected by fading, shadowing and interference. READ MORE
