We consider the problem of uniform error property (UEP) for a coded modulation with constant energy multidimensional symbols, transmitted over the additive white Gaussian noise (AWGN) or fading channels and received by a broad class of decoders. This class includes coherent, partially coherent, double differential, and noncoherent decoders, decoders designed for fading channels, decoders using ...

Execution patterns and fault distribution characteristics of a program will aaect the failure process and thus reliability estimates. The failure process of a software system is innuenced by many factors, and traditional software reliability engineering has found it diicult to isolate the eeect of each individual factor. A simulation approach is used to investigate the eeects of fault distribut...

Abslracf-For any prime-power Q, it is shown that there exist q-ary convolutional codes with the equidistance property that every code word is at the same distance from all code words disagreeing in the information digits to be decoded. These codes are called “uniform codes” and it is shown that they can be encoded in a very simple manner. The block codes most similar to uniform codes are the ma...

We developed a numerical code which allows fast and accurate simulation of isotachophoresis (ITP). The multi-species code accounts for equilibrium chemistry, non-uniform electroosmotic flow, and dispersion. Our modeling efforts for the latter are also presented. The goal of our work is to create an efficient, accurate, validated, and uniquely-capable electrophoresis simulation code available fo...

This Index lists organizations and fund condition statements in alphabetical order. The four-digit organization code represents the number assigned to a department or budget entity in the State Uniform Codes Manual. For ease of reference, budgets are in numerical order in the Governor’s Budget, and the organization code appears at the top of each page. The fund condition statements reflect the ...

LDPC codes are state-of-art error correcting codes, included in and the received samples in LDPC-coded systems using M -QAM schemes. physical layer, especially on the forward-error correction code. (FEC) performance. low-density parity check (LDPC) codes can achieve high Using long FECs with short is possible to apply a non-uniform mapping like for example. Low-density parity-check (LDPC) code ...

The recently published final regulations for transactions and code sets under HIPAA are the light at the end of the tunnel in the quest for uniform healthcare standards--and the first step on a long road to HIPAA implementation. What are the standard transactions and code sets? This article takes an in-depth look.

We consider the problem of amplifying uniform average-case hardness of languages in NP, where hardness is with respect to BPP algorithms. We introduce the notion of monotone errorcorrecting codes, and show that hardness amplification for NP is essentially equivalent to constructing efficiently locally encodable and locally list-decodable monotone codes. The previous hardness amplification resul...
