A Brief Overview and Experimental Researches of Novel PL-log-MAP Turbo Decoding Algorithm
Ch. 1. P. 1–6.
In the paper, we will discuss the powerfull class of channel codes referred to as turbo codes. We commence with a brief discussion for MAP and log-MAP decoding algorithms. Then we work with proposed turbo decoding method, which is called as PL-log-MAP. Some numerical results and research experiments, such as simulation for bit error rate estimation and images transmission have been presented. It is shown that PL-log-MAP algorithm performance is almost the same as for original log-MAP. So, this algorithm can be used in digital communication systems

Background
Persons with aphasia (PWAs) are often impaired in time reference/tense production. It has been suggested that this impairment is due to encoding or/and retrieval deficits. However, to the best of our knowledge, no experimental design that enables teasing apart selective encoding and retrieval deficits has been proposed thus far.
Aims
This study aims at disentangling time reference-related ...

Для произвольного алгеброгеометрического кода и дуального к нему явно вычислены пары, исправляющие ошибки. Такая пара состоит из кодов, которые необходимы для эффективного алгоритма декодирования заданного кода. Вид пар зависит от степеней дивизоров, с помощью которых строится как исходный код, так и один из кодов, входящих в пару. Для алгеброгеометрического кода Cl(D, G) длины n, ассоциированного ...

Recently, a modification of the classical McEliece cryptosystem has been proposed by introducing an auxiliary matrix, by which an artificial error vector is multiplied. The system was broken. In this work, we propose a simpler attack on the system, and at the same time, we propose a generalization of the system, free from the identified ...

An ultrasonic receiving and transmitting communication system for the borehole bottom-wellhead channel inside the casing pipe based on PIC18F2455 has been designed. Combined receivers-transmitters TR60-10H0Z-01 were used as piezoelectric elements. The signal frequency was 60 kHz, the encoding was “Manchester-II”. The negative impact of interference is reduced at ultrasonic frequencies, and due to the heterogeneity ...

One of the trends in the development of the lexical system of the language in Internet communication is the creation of digital codes. Numbers can be used in combination with letters, or as a pure numeric combination. The practice of using digital combinations by network users from different countries determines the relevance of this study. ...

This paper concerns new effective method of joint data coding/modulation which may improve energy-efficiency and energy savings of modern wireless transmission systems. The method require a priori knowledge of probability distribution of input data to map them to the modulation symbols in the most efficient way.
The key idea of the proposed methods of Statistical Modulation ...

In this paper we propose a generalized concatenated code (GC code) construction based on shortened Reed-Solomon inner codes and nonbinary LDPC outer codes. We also propose a soft-input decoder for this construction that makes use of soft-input soft-output decoding of both inner and outer codes. We show that this construction gives significant coding gain. We ...

In this paper we propose a woven block code construction based on two convolutional outer codes and a single inner code. We proved lower and upper bounds on this construction's code distance. The lower bound is shown to be higher than the product of the free distances of inner and outer constituent codes. Since this ...

In this paper we propose a woven block code construction based on two convolutional codes. We also propose a soft-input decoder that allows this construction to have better error correction performance than the turbo codes with a conventional decoder. Computer simulation has showed a 0.1 dB energy gain relative to the LTE turbo code. Asymptotically ...

In sample surveys, open-ended question is the only data collection tool that allows respondents to express their opinions in their own words — the advantage is especially manifested while rapid social changes when structured questionnaires do not keep pace. The main shortcoming of the open-ended question logically continues its advantage: for the researcher, it is ...
