We consider synchronization of a multi-antenna receiver for terrestrial digital video broadcasting (DVBT) in the presence of strong co-channel interference. Thereby, we use a detection approach to find the symbol starts from the received orthogonal frequency division multiplexed (OFDM) signals. We propose two algorithms that exploit different features of the DVB-T signal. Both algorithms take a...

In this work, burst oriented data transmission over unknown frequency selective channels is considered. The receiver is assumed to use multiple antennas and the problem of estimating the start position of a data packet in the presence of spatially correlated co-channel interference is addressed. Each burst is assumed to contain a known training sequence, and metrics for finding the position of ...

In the last couple of years Bluetooth has gained a large share in the market of home and personal appliances. It is now a well established technology a short range supplement to the wireless world of 802.11. The two main trends of research that have sprung from these developments are directed towards the coexistence and performance issues of Bluetooth and 802.11 as well as the coexistence in th...

It is well known that cellular capacity can be increased by reducing cell cluster size, since more channels may then be assigned to each cell. However, this reduction of cluster size leads to increased co-channel interference, requiring the use of some cochannel interference control techniques at the base stations or in the air interface. In this paper we ·analyze the combined application of "s...

In this paper, we derive a capacity inner bound for a synchronous Gaussian Z channel with intersymbol interference (ISI) under input power constraints. This is done by converting the original channel model into an n-block memoryless circular Gaussian Z channel (n-CGZC) and successively decomposing the n-block memoryless channel into a series of independent parallel channels in the frequency dom...

Linear and Non-linear distortion influenced data transmission rate in communication system. In the presence of White Gaussian Noise linear distortion occurs in form of intersymbol interference (ISI) and co-channel interference (CCI). Amplifiers, modulator and demodulator subsystems are caused for Non-linear distortions along with nature of the medium. Different techniques are used to equalized ...
