Reduced-Complexity Robust Detector in a DHA FH OFDMA System under Mixed Interference
Future generation communication systems will have to endure interference induced by communication systems operating within the same frequency bands. Recently several coded DHA FH OFDMA systems employing rank-based detectors able to solve this problem were proposed. Unfortunately such detectors have relatively high complexity. In what follows a reduced-complexity detector using only column sorting for a coded DHA FH OFDMA employing a nonbinary convolutional inner code is proposed. The proposed detector is compared with the rank convolutional detector in terms of performance, complexity and delay.

In what follows a coded DHA FH OFDMA employing robust reception and concatenated coding construction is considered. The problem of employing Generalized Minimum Distance decoder as an outer code decoder is considered. The effectiveness of the proposed decision is verified by means of simulation. In particular performance of the communication system under intensive mixed interference ...

We consider a new signal-code construction for a special class of multiple access system over vector-disjunctive channel when users transmit some vector of bits of finite length L. We propose a special encoding and decoding algorithms for such transmission scenario. Our suggested methods of encoding and decoding on one hand have acceptable complexity for a ...

We consider an uncoordinated multiple-access system that employs a modulation technique, in which the probability of suppressing the signal sent by a certain user can be considered negligible, to transmit information via a wireless channel (e.g. time hopping (TH) with pulse position modulation (PPM)).This channel can be considered as an A channel (channel without intensity ...

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.

A DHA FH OFDMA that uses order statistics- based techniques can be a very promising technique for mMTC systems. However for any case of practical interest the transmission rate of a classical DHA FH OFDMA system is relatively low due to complexity restrictions. To solve this problem a solution using concatenated coding in multiple disjoint ...
