Fast Decoding of Images With Cryptcodes for Burst Channels

Joint noncoherent demodulation and decoding for fast Rayleigh fading channels

Universal Decoding for Channels with Memory

A universal decoder for a parametric family of channels is a decoder whose structure depends on the family but not on the individual channel over which transmission takes place, and it yet attains the same random-coding error exponent as the maximum-likelihood receiver tuned to the channel in use. The existence and structure of such decoders is demonstrated under relatively mild conditions of c...

Fast Header Decoding Using Turbo Codes on Rayleigh Fading Channels

In this paper we present a modification of a typical turbo code to allow for the header bits to be decoded much faster than the other bits. This gives the decoder a possibility to discard data packets not addressed to it, and saves time and power since fewer iterations need to be performed to reliably decode the header. The proposed algorithm frequently terminates the first trellis of the turbo...

Universal Decoding for Noisy Channels

A universal decoder for a parametric family of channels is a decoder that for any channel in the family attains the same random coding error exponent as the best decoder for that particular channel. The existence and structure of such decoders is demonstrated under relatively mild conditions of continuity of the channel law with respect to the parameter indexing the family. It is further shown ...

Analysis of soft decision decoding of interleaved convolutional codes over burst channels

We study the performance of a decision feedback decoder (DFD) for convolutional codes over an interleaved burst channel. The DFD adaptively estimates channel reliability information from previous decisions. The effect of ermr propagation, finite interleaving and the length of the initial training sequence is explicitly studied. A binary Gilbert-Elliott channel is used to model the wmla t ion st...
