Super-Nyquist Rateless Coding for Intersymbol Interference Channels
نویسندگان
چکیده
A rateless transmission architecture is developed for communication over Gaussian intersymbol interference channels, based on the concept of super-Nyquist (SNQ) signaling. In such systems, the signaling rate is chosen significantly higher than the Nyquist rate of the system. We show that such signaling, when used in conjunction with good “off-the-shelf” base codes, simple linear redundancy, and minimum mean-square error decision feedback equalization, results in capacity-approaching, low-complexity rateless codes for the time-varying intersymbolinterference channel. Constructions for both single-input / singleoutput (SISO) and multi-input / multi-output (MIMO) ISI channels are developed.

Gaussian Z Channel with Intersymbol Interference
In this paper, we derive a capacity inner bound for a synchronous Gaussian Z channel with intersymbol interference (ISI) under input power constraints. This is done by converting the original channel model into an n-block memoryless circular Gaussian Z channel (n-CGZC) and successively decomposing the n-block memoryless channel into a series of independent parallel channels in the frequency dom...
متن کاملJoint source channel coding over channels with intersymbol interference using vector channels and discrete multitone
We investigate joint source channel coding for channels with intersymbol interference (ISI) where the source coder is a vector quantizer. In our previous work we used a block MAP equalizer, which takes into account the residual correlation between the VQ outputs and also provides for soft decisions to improve the performance. In this paper we propose the use of a vector channel approach and dis...
متن کاملOn the low-rate Shannon limit for binary intersymbol interference channels
For a discrete-time, binary-input Gaussian channel with finite intersymbol interference (ISI), we prove that reliable communication can be achieved if and only if Eb=N0 > log 2=Gopt, for some constant Gopt that depends on the channel. To determine this constant, we consider the finite-state machine which represents the output sequences of the channel filter when driven by binary inputs. We then...
متن کاملNyquist Filters with Alternative Balance between Time- and Frequency-Domain Parameters
Designing matched pulse shaping filters with their cascade satisfying the Nyquist condition for minimum intersymbol interference constitutes an important task for almost all digital data radio transceivers processing an incoming data signal on the sampleby-sample basis. Despite their practical importance, there are only few sets of Nyquist filter definitions and design techniques to devise digi...
متن کاملA Review on Design and Applications of Nyquist Filter
A humongous development in the study of Nyquist filter has been observed in the recent years. This paper presents a review of the work done on a Nyquist filter in the last decade. Nyquist filter is called M th band filter because it has zero coeffient at every M th sample except its middle coefficient. Different filter methods have been proposed with the focus of improving filter parameters lik...
