Wireless Testbed Receiver
These days, the demand for mobile transmission bandwith seems to be a never ending story. To get insights into the real world, wireless transmission measurements and not only simulations of mobile communication systems are necessary. For this task, the Vienna Wireless Testbed has been developed. To keep pace with future developments, the testbed has to be extended and updated constantly. Furthe...
متن کاملDesign of an OFDM receiver for high-speed wireless LAN
In this paper. we propose a baseband OFDM receiver for highspeed wireless local area network defined in IEEE 802.1 la physical layer. Algorithms for channel estimation/equalization. timing recovery, carrier frequency acquisition/tracking, and sampling clock tracking are individually designed and later integrated into a receiver architecture. Simulation results show that the proposed OFDM receiv...
متن کاملA sectored receiver for infrared wireless networks
This paper presents an experimental sectored receiver for infrared wireless networks. The receiver comprises two sectors, each with a switched gain front-end and a signal-to-noise ratio estimator. These are then interconnected with a best-sector selector unit, able to compensate the gain switching characteristics of the front-ends. The circuit has been designed in a 0.8μm CMOS technology.
متن کاملSignal Processing for Improved Wireless Receiver Performance
This thesis is concerned with signal processing for improving the performance of wireless communication receivers for well-established cellular networks such as the GSM/EDGE and WCDMA/HSPA systems. The goal of doing so, is to improve the end-user experience and/or provide a higher system capacity by allowing an increased reuse of network resources. To achieve this goal, one must first understan...
متن کاملReceiver Architectures for FMT Broadband Wireless Systems
Orthogonal Frequency Division Multiplexing (OFDM) and in particular Discrete Multitone (DMT) modulation has been proposed for the physical layer of wideband wireless local area networks. As an alternative, Filtered Multitone (FMT) modulation can be also considered, since it exhibits significantly lower spectral overlapping between adjacent subchannels, so providing higher transmission efficienc...
