Rate-distortion and complexity optimized motion estimation for H.264 video coding
(IEEE-INST Electrical Electronics Engineers Inc, 2008-02)
11.264 video coding standard supports several inter-prediction coding modes that use macroblock (MB) partitions with variable block sizes. Rate-distortion (R-D) optimal selection of both the motion vectors (MVs) and the ...
On the spectral correlation of UWB impulse radio signals
(IEEE-INST Electrical Electronics Engineers Inc, 2008-10)
Cyclostationarity is an inherent characteristic of many communication signals, which can be exploited for performing various signal processing tasks. Determining the cyclic statistics of a signal of interest is often ...
On the cyclostationary statistics of ultra-wideband signals in the presence of timing and frequency jitter
(Elsevier GMBH, Urban & Fischer Verlag, 2008)
Cyclostationarity is an inherent characteristic of many man-made communication signals, which, if properly recognized, can be exploited for performing various signal-processing tasks. Determining the cyclostationary ...
Design and performance analysis of a novel trellis coded space-time-frequency OFDM transmission scheme
(Wiley-Blackwell, 2008-01)
In this paper a new transmit diversity technique is proposed for wireless communications over frequency selective fading channels. The proposed technique utilises orthogonal frequency division multiplexing (OFDM) to transform ...
Integration of 2D CMUT arrays with front-end electronics for volumetric ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2008-02)
For three-dimensional (3D) ultrasound imaging, connecting elements of a two-dimensional (2D) transducer array to the imaging system's front-end electronics is a challenge because of the large number of array elements and ...
