1. Detection principles for fast Rayleigh fading channels using an antenna array
Sammanfattning : .... LÄS MER
2. Short-Packet Communications: Fundamental Performance and Key Enablers
Sammanfattning : The paradigm shift from 4G to 5G communications, predicted to enable new use cases such as ultra-reliable low-latency communications (URLLC), will enforce a radical change in the design of communication systems. Unlike in 4G systems, where the main objective is to have a large transmission rate, in URLLC, as implied by its name, the objective is to enable transmissions with low latency and, simultaneously, very high reliability.

3. Coding for multiple-access and fading channels
Sammanfattning : This thesis treats some information-theoretical and coding aspects of communication over multiple-access and fading channels. It consists of a general introduction and seven papers. In code-division multiple-access (CDMA) communication, many users have access to the channel simultaneously. LÄS MER
4. The Information-Theoretic Cost of Learning Fading Channels
Sammanfattning : Recent results in communication theory suggest that significant throughput gains in wireless fading networks can be achieved by exploiting network coordination (e.g., CoMP, network MIMO, and interference alignment), provided that each node in the network has perfect channel knowledge.

5. Efficient Digital Communication over the Time Continuous Rayleigh Fading Channel
Sammanfattning : Frequency flat, fast Rayleigh fading may be considered the most critical disturbance in a wireless communication system. In its most general form, it is modeled as a multiplicative time continuous random (zero mean complex Gaussian) distortion of the transmitted signal. LÄS MER
