A New Successively Decodable Coding Technique for Intersymbol-Interference Channels
نویسندگان
چکیده
For the Gaussian channel with intersymbolinterference (ISI), it is known that there is no loss in channel capacity if the receiver is an ideal minimum mean-squared error (MMSE) decision-feedback equalizer (DFE) with error-free feedback. However, combining the DFE with channel coding is problematic. Transmitter precoding and reduced-state sequence estimation are two common approaches (cf. [1] and references therein). This paper introduces a new successively-decodable coding technique that effectively combines channel coding with decision-feedback that is housed in the receiver. I. THE CHANNEL MODEL Consider the real-valued discrete-time Gaussian channel with intersymbol interference (ISI) represented by

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 کاملThe Expected Achievable Distortion of Two-User Decentralized Interference Channels
This paper concerns the transmission of two independent Gaussian sources over a two-user decentralized interference channel, assuming that the transmitters are unaware of the instantaneous CSIs. The availability of the channel state information at receivers (CSIR) is considered in two scenarios of perfect and imperfect CSIR. In the imperfect CSIR case, we consider a more practical assumption of...
متن کاملA Class of Block-Iterative Equalizers for Intersymbol Interference Channels
A new and efficient class of nonlinear equalizers is developed for intersymbol interference (ISI) channels. These “iterated-decision equalizers” use an optimized multipass algorithm to successively cancel ISI from a block of received data and generate symbol decisions whose reliability increases monotonically with each iteration. These equalizers have an effective complexity comparable to the d...
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 کاملIterative packet combining schemes for intersymbol interference channels
We study packet combining techniques for retransmission schemes over intersymbol interference (ISI) channels. Two types of combining schemes are investigated, namely, maximumlikelihood combining (MLC) and iterative combining (IC). By first employing a precoding technique and then by interpreting the ISI channel as a trellis code, the transmissions of the same data packet at different times thro...
