Unequal error-protection (UEP) codes that are designed using trellis-coded modulation (TCM) are proposed for use with a single data stream consisting of information with two levels of importance. To achieve UEP, the proposed scheme encodes the data according to the importance of the information by switching between two codes which use different signal constellations. Using simple trellis codes,...

Single nucleotide polymorphisms (SNPs) are currently being developed for use in disequilibrium analyses. These SNPs consist of two alleles with varying degrees of polymorphism. A natural design for use with SNPs is the 'haplotype relative risk' sampling design in which a father, mother, and child are typed at an SNP locus. Given such a trio of genotypes, we ask: what is the probability that a p...

In this paper, we propose a cross-layer design which combines Packet Forward Error Correction (P-FEC) at the application layer with a Symbol unequal FEC in the MAC layer (S-FEC). The aim is to minimize the Packet Loss Rate (PLR) and maximize the visual quality of video transmitted over a wireless network (WN). The proposed scheme is based on a FEC compatible with the semantics of the H.264/AVC ...

A modified linear discriminant analysis technique for speaker verification, referred to here as normalized discriminant analysis (NDA), is presented. Using this technique it is possible to design an efficient linear classifier with very limited training data and to generate normalized discriminant scores with comparable magnitudes for different classifiers. The NDA technique is applied to a cla...

Error probability of an adaptive multiuser diversity receiver is evaluated in terms of channel fading rate and the number of code-division multiple access users. Fading-induced performance loss, which leads to error probability floor, is established for the proposed coherent combining scheme and compared to that of differentially coherent receiver with equal-gain combining.

in the present work, the effects of operating conditions including ph, transmembrane pressure, oil concentration, and temperature on fouling resistance and the rejection of turbidity for a polymeric membrane in an ultrafiltration system of wastewater treatment were studied. a new modeling technique called evolutionary polynomial regression (epr) was investigated. epr is a method based on regres...

Performance of differential phase-shift keying (DPSK) is considered for fading channels with nonnegligible time-variation, as well as signal or noise correlation between diversity branches. A differentially coherent maximum-ratio combiner is derived, showing optimal weight dependence on the fading statistics. Bit error rate (BER) is evaluated analytically for Rayleigh fading, and comparison is ...
