Coding for a Terrible Channel
نویسنده
چکیده
We describe coding and modulation aspects for a channel with different kinds of a-typical noise disturbances. An example of such a channel is the powerline communication (PLC) channel, but the same noise disturbances can be observed in for instance xDSL communications. The channel is assumed to suffer from background noise, impulsive noise, narrowband noise and fading. In addition, in PLC, the signal attenuation can go up to 100dB/Km. This causes a problem for distances of the order of 100m-1000m. We concentrate on M-FSK as a modulation technique and look at the coding aspects that follow from this choice.

An efficient secure channel coding scheme based on polar codes
In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...
متن کاملAchievable Secrecy Rate Regions of State Dependent Causal Cognitive Interference Channel
In this paper, the secrecy problem in the state dependent causal cognitive interference channel is studied. The channel state is non-causally known at the cognitive encoder. The message of the cognitive encoder must be kept secret from the primary receiver. We use a coding scheme which is a combination of compress-and-forward strategy with Marton coding, Gel’fand-Pinsker coding and Wyner’s wire...
متن کاملتجزیه و تحلیل عملکرد کدهای کانولوشنال تعریف شده در میدان حقیقی در کانال فیدینگ و در حضور نویز کوانتیزاسیون
Channel coding is one of the techniques used for suppression of fading and channel noise effects. Most of the researches on channel codes have been focused on the codes which are defined on Galois fields. Since two decades ago, using channel codes defined on Real and Complex fields has been considered for joint sourcechannel coding in multimedia transmission; but most of the works have focused ...
متن کاملPower Allocation Strategies in Block-Fading Two-Way Relay Networks
This paper aims at investigating the superiority of power allocation strategies, based on calculus of variations in a point-to-point two-way relay-assisted channel incorporating the amplify and forward strategy. Single and multilayer coding strategies for two cases of having and not having the channel state information (CSI) at the transmitters are studied, respectively. Using the notion of cal...
متن کاملBounds for Multiple-Access Relay Channels with Feedback via Two-way Relay Channel
In this study, we introduce a new two-way relay channel and obtain an inner bound and an outer bound for the discrete and memoryless multiple access relay channels with receiver-source feedback via two-way relay channel in which end nodes exchange signals by a relay node. And we extend these results to the Gaussian case. By numerical computing, we show that our inner bound is the same with o...
