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...

HARQ Aided Systematic LT Coding for Amplify-Forward and Decode-Forward Cooperation
—Systematic Luby Transform (SLT) codes constitute rateless codes, which are capable of adaptively adjusting their code rate depending on the channel quality without explicit chan...

Lower Bounds on the Rate-Distortion Function of LDGM Codes
Abstract-- We analyze the performance of low-density generator matrix (LDGM) codes for lossy source coding. We first develop a generic technique for deriving lower bounds on the ef...

Fast Lossy Internet Image Transmission
Images are usually transmitted across the Internet using a lossless protocol such as TCP/IP. Lossless protocols require retransmission of lost packets, which substantially increas...
