Low complexity inter-mode selection for H.264
(IEEE, 2006)
The coding efficiency of the H.264/AVC standard enables the transmission of high quality video over bandwidth limited networks. Due to the use of multiple Macroblock (MB) partitions, the Motion estimation module has extremely ...
A cost-efficient bit-serial architecture for sub-pixel motion estimation of H.264/AVC
(IEEE Computer Soc, 2008)
This paper presents a new VLSI architecture for sub-pixel motion estimation in H.264/AVC encoder. It is based on an interpolation free algorithm that causes a high level reduction on memory requirement, hardware resources ...
A novel noise robust and low bit rate speech coding algorithm
(IEEE, 2009)
In this work, a new noise robust and variable length frame based speech modeling method is introduced. This method consists of three major steps which includes noise removal algorithm, coding and encoding algorithms, ...
Achievable rates for two user cooperative OFDMA
(IEEE, 2010)
We propose two encoding strategies for a two user cooperative Orthogonal Frequency Division Multiple Access (OFDMA) system, based on block Markov superposition encoding. We obtain the expressions for the resulting achievable ...
A novel representation method for electromyogram (EMG) signal with predefined signature and envelope functional bank
(IEEE, 2004)
In this paper, a new method to model EMG signals by means of "Predefined Signature and Envelope Functional Banks (PSEB)" is presented. Since EMG signals present quasi-stationary behavior, any EMG signal Xi is modeled by ...
Optimal primary-secondary user pairing and power allocation in cognitive cooperative multiple access channels
(IEEE, 2014)
We develop jointly optimal power control and primary-secondary user partnering strategies for a cognitive cooperative multiple access channel with K primary and K secondary users. For each primary user, a cooperating ...
Optimum power control for transmitter cooperation in OFDMA based wireless networks
(IEEE, 2011)
For a cooperative orthogonal frequency division multiple access (OFDMA) system with two transmitters (TXs), and full channel state information (CSI), we obtain the optimal power allocation (PA) policies which maximize the ...
Decoder side true motion estimation for very low bitrate b-frame coding
(IEEE, 2011)
In H.264 standard, coding of motion vectors constitutes a significant portion of total bitrate especially at low bitrate regimes. This is because differential coding of motion vectors is inefficient when the bit budget is ...
Decoder-side super-resolution and frame interpolation for improved H.264 video coding
(IEEE, 2013)
In literature decoder-side motion estimation is shown to improve video coding efficiency of both H.264 and HEVC standards. In this paper we introduce enhanced skip and direct modes for H.264 coding using decoder-side ...
Delay tolerant cooperation in the energy harvesting multiple access channel
(IEEE, 2016)
We consider the optimum transmit scheduling problem for a two user energy harvesting cooperative multiple access channel. We assume a slotted model where energy harvests in each slot are known a priori. We propose a delay ...
