Spread Codes and Spread Decoding in Network Coding
In this paper we introduce the class of Spread Codes for the use in random network coding. Spread Codes are based on the construction of spreads in finite projective geometry. The ...

Soft-Bit Assisted Iterative AMR-WB Source-Decoding and Turbo-Detection of Channel-Coded Differential Space-Time Spreading Using
Abstract – Jointly optimised iterative source- and channel-decoding is used for enhancing the error resilience of the Adaptive Multi Rate WideBand (AMR-WB) speech codec. The resu...

A Framework of Multiplicative Spread Spectrum Embedding for Data Hiding: Performance, Decoder and Signature Design
In this paper, we have investigated several aspects of multiplicative spread spectrum (MSS) embedding for Data Hiding. First, we analyze the probability of error of the maximum lik...

Implementation of message-passing algorithms for the acquisition of spreading codes
A new technique to acquire pseudo-noise (PN) sequences has been recently proposed in [1] and [2]. It is based on the paradigm of iterative Message Passing (iMP) to be run on loopy...
