The use of active narrowband interference (NBI) suppression in direct-sequence spread-spectrum (DS-SS) communications has been extensively studied. In this paper, we address the problem of optimum coding–spreading tradeoff for NBI suppression. With maximum-likelihood (ML) decoding, we first derive upper bounds on the error probability of coded systems in the presence of a special class of NBI, namely,...
The linear coding methods for image classification work by projecting each local descriptor into the codebook, and making a tradeoff between minimizing the projection error and representation sparseness or locality. In this procedure, it is inevitable to lose some discriminative information which may be very important for image classification. In this paper, we alleviate the information loss in the...
In this paper, iterative differential phase-shift keying (DPSK) demodulation and channel decoding scheme is investigated for the Joint Channel decoding and physical layer Network Coding (JCNC) approach in two-way relaying systems. The Bahl, Cocke, Jelinek, and Raviv (BCJR) algorithm for both coherent and noncoherent detection is derived for soft-in soft-out decoding of DPSK signalling over the two-user...
In this paper, Spatial Correlation-based Distributed Compressed Sensing (SCDCS) model and algorithm are presented in Wireless Sensor Networks (WSN), where spatial correlation and joint sparse models between the sensor nodes can be exploited in order to compress and reconstruct sensor observations in an energy efficient manner based on coding/decoding algorithm of SCDCS. Finally, the analysis of relationship...
β-ketoacyl-ACP synthetase II (KAS II) which catalyzes the elongation of 16:0-ACP to 18:0-ACP, determines the ratio of palmitic acid (16:0) to stearic acid (18:0). Using Rapid Amplification of cDNA Ends (RACE) and a peanut cDNA library we had previously constructed, we isolated a 1867bp cDNA of the KAS II gene containing a 1212bp complete open reading fragment (ORF). Sequence analysis revealed that...
