16. Detection in Digital Communication Systems with Phase Noise
Sammanfattning : In every communication system, the limitations of the hardware sets a constraint on the overall system performance. More often than not, these limitations are not taken into account during the system design stage where the hardware is considered ideal. LÄS MER
17. Channel Related Optimization of Wireless Communication Systems
Sammanfattning : This thesis deals with different optimization problems in the design of wireless communication systems. It is mainly directed to the design of systems based on multicarrier techniques and orthogonal frequency division multiplex, OFDM, but some of the problems apply to single carrier systems as well. LÄS MER
18. Digital communication in wireline and wireless environments
Sammanfattning : This thesis consists of an introduction and five parts dealing with digital communication. Three parts address Discrete Multi-Tone modulation (DMT), a wireline form of Orthogonal Frequency Division Multiplexing (OFDM). LÄS MER
19. Low-density parity-check codes : unequal error protection and reduction of clipping effects
Sammanfattning : The invention of low-density parity-check (LDPC) codes made reliable communication possible at transmission rates very close to the theoretical limit predicted by Shannon. However, communication close to the Shannon limit requires very long codes and results in long delay and high encoder and decoder complexity. LÄS MER
20. Studies on implementation of low power FFT processors
Sammanfattning : In the last decade, the interest for high speed wireless and on cable communication has increased. Orthogonal Frequency Division Multiplexing (OFDM) is a strong candidates and has been suggested or standardized in those communication systems. LÄS MER
