This paper proposes an energy-efficient Network-on-Chip (NoC) topology called ZMesh, which is targeted towards the class of Constant-Geometry (CG) algorithms as well as generic traffic patterns. A simple technique has been followed to map functions to cores. The communication and traffic patterns of the considered algorithm class have been considered in synthesizing the proposed topology. The topology...
We propose a verification-based algorithm for noiseless Compressed Sensing that reconstructs the original signal operating on a sparse graph. The proposed scheme has affordable computational complexity and its performance is significantly better than previous verification-based algorithms and similar to AMP-based algorithms. We also show that the performance of a noiseless compressed sensing scheme...
This paper presents a shared Key Equation Solver (KES) architecture based on inversion-less Peterson algorithm for Concatenated Bose-Chaudhuri-Hocquenghem (CBCH) decoder. In the conventional CBCH decoding approaches, the KES module has been implemented based on advanced Simplified inversion-less Berlekamp-Massey (SiBM) to reduce circuit area. However, the long latency of the advanced SiBM has been...
Multi-class learning is an important task in Data Science. One of the ways to achieve good performance on this task is to use Error Correcting Output Codes (ECOC), which is a powerful ensemble learning method that transforms a multi-class problem into a series of binary classifiers which it uses indirectly to learn the original multi-class problem. A crucial component of ECOC is the design of the...
A class of rate-compatible (RC) quasi-cycle low-density parity-check (QC-LDPC) codes that have linear encodable complexity and low error floor is presented. To ensure linear encoding complexity, a lower triangular (LT) form for the parity part of the mother parity-check matrix is designed. By the designed LT form, a recursive encoding strategy is proposed. This encoding strategy can achieve linear...
The pioneering findings of Yarbus have been replicated in recent times to decipher specific tasks from eye gaze. In this study, we focused on analyzing factors that affect task decoding using Hidden Markov Models in an experiment with different pictures and tasks. Three pictures were chosen along with four questions each for the subjects to perform several visual and cognitive tasks. Areas of interest...
In order to achieve error correction nearer to Shanon's limit, Turbo decoder imparts either Soft Output Viterbi Algorithm (SOVA) or Maximum Posteriori Probability (MAP). The feasibility of most expected path through the Trellis is mainly determined by Max-Log-MAP, a Soft Input Soft Output (SISO) algorithm and gives a better performance over MAX-LOG-MAP (MLMAP) algorithm. To improve the decoder's performance...
Error-control coding pattern is used in modern communication system to uplift the immunity of noisy communication channel by adding the redundant bits. Suitable tuning of internal parameters of constituent codes leads to considerable enhancement in system performance of Turbo code under AWGN channel condition. In this paper, an optimized Serially Concatenated Convolution Turbo Code (SCCTC) has been...
With the increasing demand of transmission speed and more robust quality of service, the capacity constrained backhaul gradually becomes bottleneck in cooperative wireless networks, e.g. in Joint Processing mode of LTE-Advanced Pro. This paper focuses the fact of resource allocation with limited backhaul capacity in uplink cooperative networks, where two base stations (BS) equipped with single-antenna...
Resistive random access memory (RRAM) has been recognized as one of the most promising candidates for next generation non-volatile memory due to its simple structure and excellent scalability. However, poor reliability is a serious issue for RRAM memory applications. To improve the reliability and endurance, many researchers changed the cell material, process and structure. Here, in this paper, we...
SPIHT algorithm is well known reference for image coding algorithms. In this paper we present its specific extension called SM SPIHT related to region of interest encoding (ROI) but extending this approach further, ending with individual weight of importance for each pixel in image using the form of saliency map (SM). With carefully designed saliency map the approach has proven to be effective. The...

To get a generalized version of LDPC code, we construct (7, 4)-Hamming GLDPC code with (7, 4) Hamming component code in this paper, and give the number of short cycles of this GLDPC code as well as the code weight distribution. Via MLD, the negative effects of short cycles limited in the Hamming block can be eliminated. Simulation results show that, up to 2 dB coding gain can be obtained for GLDPC...

Among the linear precoding techniques block diagonalization (BD) based schemes are well-known transmit strategies employed in the downlink of multiuser MIMO (MUMIMO) systems. Employing BD type precoding algorithms at the transmit side suppresses multi-user interference (MUI) by converting a MU-MIMO broadcast channel into multiple single-user MIMO (SU-MIMO) channels and then decomposing the SU-MIMO...

This paper considers the problem of parameter tracking in wireless sensor networks. The sensor nodes observe a random vector source that varies according to a state-space model, and perform linear precoding on the observations, before coherently transmitting them to the fusion center. The fusion center then linearly decodes the received vector in order to recover the source vector. Compared to the...
