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 also compared it to generalized error-location codes with Reed-Solomon component codes and hard-decision decoding. We believe that the proposed code could be used in modern and future radio communication systems.

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 ...

n this paper we propose to consider a generalized error-locating code (GEL-code) as a possible candidate for data transmission systems that require high code rates along with strict requirements on wrong decoding probability. The paper describes the construction of the GEL-code and the algorithms for encoding and decoding. The main idea is to implement a ...

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 ...

Separating codes have been used in many areas as diverse as automata synthesis, technical diagnosis and traitor tracing schemes. In this paper, we study a weak version of separating codes called almost separating codes. More precisely, we derive lower bounds on the rate of almost separating codes. From the main result it is seen that ...

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 ...

Coded DHA FH OFDMA communication systems that use order statistics-based detectors are promising candidates for applications such as IoT and M2M. For the majority of order statistics-based reception techniques the high throughput coded modulation schemes development remains an open problem. In what follows a novel order-statistics based detector that outperforms the classical Maximum Rank Sum ...

Multiple-input multiple-output systems are communication systems employing multiple transmitting and receiving antennas. In the present study, a new generalized concatenated signal-code construction is proposed. Its inner codes are embedded Golden codes, and its outer codes are products of Reed-Solomon codes. New algorithms for decoding inner codes, outer codes, and the generalized signal-code construction itself are ...
