  1. 21. Adaptive Subband Equalization in Wireless Systems

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Alvaro Palomo Navarro; [2006]
    Keywords : adaptive; subband; equalization;

    Abstract : The trend in communication is very clear; everything goes towards wireless communication systems. Since, the wireless channel is very hostile channel due to capacity limiting effects like co-channel interference, inter symbol interference, multi-path propagation and noise, these system require very good channel equalizers in order to combat these effects.

  3. 22. Real-time Modeling and Analysis of a Multiple-Input-Multiple-Output (MIMO) Wireless System over Acoustic Channel

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Farhan Khalid; [2005]
    Keywords : Acoustic channel; channel estimation; MIMO equalization; MIMO wireless system; Singular Value Decomposition SVD ;

    Abstract : Multiple-input-multiple-output (MIMO) wireless systems employ multiple transmitter and receiver antennas, and offer a manifold increase in system capacity and improvement in signal quality, as compared to conventional wireless systems being used at present. MIMO uses spatial multiplexing and exploits multipath propagation to its benefit for increasing system capacity as opposed to conventional wireless systems, while the spatial diversity at the transmitter as well as the receiver ensures better signal quality in terms of the bit-error rate (BER).

  4. 23. Use of equalization and echo canceling on circuit board wires

    University essay from Institutionen för systemteknik

    Author : Andrew Guzeev; [2002]
    Keywords : Electronics; Intersymbol Interference; DDR; adaptive equalizer; filter; memory; Elektronik;

    Abstract : Advances in CMOS technology have resulted in increased clock fre-quencies, even exceeding 3GHz. At the same time, frequencies on most board wires are 125-800MHz. It is especially problematic in modern computer mem-ory buses and high speed telecommunication devices, such as switches and routers operating at 10Gb/s on its ports. READ MORE

  5. 24. Equalization of Audio Channels : A Practical Approach for Speech Communication

    University essay from Blekinge Tekniska Högskola/Institutionen för telekommunikation och signalbehandling

    Author : Nils Westerlund; [2000]
    Keywords : Speech enhancement; channel equalization; deconvolution; inverse filtering; ear-muff;

    Abstract : Many occupations of today requires the usage of personal preservative equipment such as a mask to protect the employee from dangerous substances or the usage of a pair of ear-muffs to damp high sound pressure levels. The goal of this Master thesis is to investigate the possibility of placing a microphone for communication purposes inside such a preservative mask as well as the possibility of placing the microphone inside a persons auditory meatus and perform a digital channel equalization on the speech path in question in order to enhance the speech intelligibility.
