Mitigating the amount of overhead arising from the control signaling of the IEEE 802.16 OFDMa system
This work focuses on mitigating the amount of overhead arising from the control signaling of the IEEE 802.16 system. It analyses existent solutions and proposes efficient methods and algorithms. Although existent IEEE 802.16 standard proposes some techniques, it is worthwhile to point out that exact implementation is not specified and left open for alternative implementations. The first part of this work addresses the main aspects of MAC layer overhead. The second part of this work introduces efficient techniques to improve the performance of ARQ mechanism. It is shown that the ARQ mechanism can improve significantly the performance of TCP based applications and confirms that a correct configuration plays an important role in transmitting data over wireless channels in the IEEE 802.16 OFDMa system. It is also of the view that the proposed solutions in this work must be verified by means of extensive simulations, and therefore each proposed method and algorithm is implemented and tested within the WINSE simulator in the NS-2 framework.

Synchronization and blind signal processing in CDMA systems
Ristaniemi, Tapani (2000)In this thesis we consider signal processing in the Direct-Sequence (DS) Code Division Multiple Access (CDMA) systems. We pay special attention to the downlink (e.g. mobile phone) environment, where the knowledge of the ... -
Content, cost, and context : A framework for understanding human signaling systems
Barker, Jessica L.; Power, Eleanor A.; Heap, Stephen; Puurtinen, Mikael; Sosis, Richard (John Wiley & Sons, Inc., 2019)Humans frequently perform extravagant and seemingly costly behaviors, such as widely sharing hunted resources, erecting conspicuous monumental structures, and performing dramatic acts of religious devotion. Evolutionary ... -
Targeting the Activin Receptor Signaling to Counteract the Multi-Systemic Complications of Cancer and Its Treatments
Hulmi, Juha J.; Nissinen, Tuuli A.; Penna, Fabio; Bonetto, Andrea (MDPI, 2021)Muscle wasting, i.e., cachexia, frequently occurs in cancer and associates with poor prognosis and increased morbidity and mortality. Anticancer treatments have also been shown to contribute to sustainment or exacerbation ... -
Weakly controlled Moran constructions and iterated functions systems in metric spaces
Rajala, Tapio; Vilppolainen, Markku (University of Illinois, 2011)We study the Hausdorff measures of limit sets of weakly controlled Moran constructions in metric spaces. The separation of the construction pieces is closely related to the Hausdorff measure of the corresponding limit set. ... -
