An Efficient Algorithmic Lower Bound for the Error Rate of Linear Block Codes
IEEE Transactions on Communications, 2007We present an efficient algorithmic lower bound for the block error rate of linear binary block codes under soft maximum-likelihood decoding over binary phase-shift keying modulated additive white Gaussian noise channels. We cast the problem of finding a lower bound on the probability of a union as an optimization problem that seeks to find the subset ...

Evaluation of the Extremely Low Block Error Rate of Irregular LDPC Codes
2009 IEEE International Conference on Communications, 2009In this paper, we attempt to evaluate irregular LDPC code performance at the high SNR region using the importance sampling (IS) approach in conjunction with primary-trapping-set identification. Results have indicated that our proposed IS scheme can produce speed-up gains up to 3.9 × 109 times compared with Monte Carlo simulations.

Reduced-rate block truncation coding of images using error diffusion
IEEE Signal Processing Letters, 1995We consider a simple modification to classical block truncation coding (BTC) that may permit the use of larger block sizes for some applications. although BTC is favored for its simple encoding and decoding, its disadvantage is the relatively low compression ratio achieved.

Journal of Motor Behavior, 1983
The degree to which blocked (VE) data satisfies the assumptions of compound symmetry required for a repeated measures ANOVA was studied. Monte Carlo procedures were used to study the effect of violation of this assumption, under varying block sizes, on the Type l error rate. Populations of 10,000 subjects for each of two groups, the underlying variance-

Symbol Error Rate of Binary Block Codes
1983Symbol error rate versus error probability for the binary symmetric channel is evaluated for perfect binary codes, i.e. repetition codes (2m+1, 1, 2m+1), Hamming codes (2m−1, 2m−1−m, 3) and Golay code (23, 12, 7), and for the parity check codes (n+1, n, 2).

Block Error Rate Analysis of Short-Packet NOMA Communications with Imperfect SIC
2020 IEEE/CIC International Conference on Communications in China (ICCC), 2020In this paper, we study the cellular internet of things (IoT) with multi-user short-packet communications. To achieve low-latency as well as a high spectral efficiency, non-orthogonal multiple access (NOMA) technique is adopted. Considering the practical scenario with imperfect successive interference cancellation, this paper provides a detailed ...

Decoding linear block codes for minimizing word error rate (Corresp.)
IEEE Transactions on Information Theory, 1979Two modifications of the basic correlation decoding approach are presented. One of them yields a nonexhaustive optimum word decoding algorithm whose complexity depends upon the "projecting" structure of the code. This algorithm is then modified to yield a second decoding algorithm which, while not optimum, has simpler complexity.

Impact evaluation of logic blocks configuration on FPGA's soft error rate estimation
2016 IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2016The Soft Error Rate (SER) of an electronic system depends on its sensitivity to the transient faults on its internal elements. Therefore, the SER is commonly estimated by injecting faults into these elements, using a uniform fault distribution. Although this approach can adequately support a feasibility or a compliance analysis, a more accurate ...

Block-error rate model for DPSK in Rayleigh- and sub-Rayleigh-fading channels
IEEE Journal on Selected Areas in Communications, 2005Wireless transmission channels experience substantial signal degradation due to irregularities in the propagation path that impact synchronization between two communicating ends. Consequently, differential and noncoherent techniques that require no such synchronization have gained wide popularity. However, the transmitted data are still highly prone to

Minimum Bit Error Rate beamforming combined with Space-Time Block Coding
2011 International Conference on Communications and Information Technology (ICCIT), 2011In this paper, we propose a Minimum Bit Error Rate (MBER) beamforming combined with Space-Time Block Coding (STBC) according to the number of antenna array. A class of adaptive beamforming algorithm has been proposed based on minimizing the BER cost function directly.
