Meijer, J.F. (author)The Packet Reservation Multiple Access protocol can be used in wireless communication systems and enables dispersed terminals to transmit packetized information over a shared communication channel. The performance of the protocol depends on the values of the system variables and is calculated using a mathematical model. Besides a mathematical...master thesis 1992

Satyanegara, H. (author)In this thesis, the performance of star connected direct sequence spread spectrum (DS/SS) slotted code division multiple access (CDMA) systems in an indoor radio environment characterized by Rician fading has been examined. The performance parameters are the throughput, steady state delay and stability (namely the expected drift and state...master thesis 1993

Punt, J.B. (author)Dynamic Channel Selection is an algorithm for allocating channels in a mobile wireless environment. The channels are not allocated according to location, but according to channel quality at the time of use. A mathematical model for Dynamic Channel Allocation as defined in the Digital European Cordless Telecommunication Standard was extended and...master thesis 1994

Munne, R. (author)This report gives first an overview of the main modulation methods and of the multipath propagation effects. A model is described to simulate BPSK, QPSK and OK-QPSK in some measured indoor channels. Several pulse shapes are analysed and their effects discussed on single-user systems and on DS-CDMA. The main performance parameter is the bit error...master thesis 1996

Spaans, K. (author)Abstract - The objective is to design a suitable protocol for error-correction that is to be used in a multi-carrier wireless communication system in a multipath channel. Different kinds of codewordmapping are applied, that should enhance the errorcorrecting capabilities of existing codes. Simulations of the system are run to examine if this is...master thesis 1999

Rousseaux, O. (author), Leus, G. (author), Moonen, M. (author)To allow for a computationally efficient equalization scheme for the frequency-selective transmission channels encountered in wireless local area network (WLAN) applications, cyclic prefix (CP) block transmission schemes have been proposed, such as single-carrier CP (SC-CP) and multi-carrier CP (MC-CP) transmission, also known as orthogonal...journal article 2007

Kiyani, N.F. (author)The next generation communication devices are foreseen to not only support a large variety of applications, ranging from speech, audio and video graphics but also be able to maintain connection with many other devices (rather than a single base station) in different changing environments. The aim of the dissertation is to analyze digital...doctoral thesis 2009

Waasdorp, P.A.C. (author)Assume that two sub-graphs of a graph are available and that the graph represents the corridors in a building. Without using any previous knowledge on the entire graph, can these two sub-graphs be used to construct an extended view on the entire graph. To test this assumption a collection of algorithms will be designed and implemented which can...master thesis 2010

Venkateswaran, V. (author)One of the major drawbacks towards the realization of MIMO and multi-sensor wireless communication systems is that multiple antennas at the receiver each have their own separate radio frequency (RF) front ends and analog to digital converter (ADC) units, leading to increased circuit size and power consumption. Improvements in RF and ADC...doctoral thesis 2010

Zhou, J. (author)Nowadays, wireless networks are used in most of the applications with radio technologies being used in all kinds of wireless networks. In all wireless links, the transmitted packets can be lost. How to identify the quality of a certain wireless link and achieve the best delivery performance over a certain wireless network is an open issue. In...doctoral thesis 2010

Bolatkale, M. (author), Breems, LJ (author), Rutten, Robert (author), Makinwa, K.A.A. (author)A 4 GHz third-order continuous-time ΔΣ ADC is presented with a loop filter topology that absorbs the pole caused by the input capacitance of its 4-bit quantizer and also compensates for the excess delay caused by the quantizer's latency. The ADC was implemented in 45 nm-LP CMOS and achieves 70 dB DR and -74 dBFS THD in a 125 MHz BW, while...journal article 2011

Kotobi, K. (author)The studies about the effects of multipath fading and shadowing for wireless cooperative networks are insufficient. Almost all real wireless networks can be modeled by changing the parameters of the composite distribution which models both multipath and shadow fading. This composite distribution makes the analytical calculation of bit error rate...master thesis 2011
