Distributed LT Codes with Unequal Error Protection
In this paper, we present a method to provide unequal error protection (UEP) for distributed sources in a two-source single-sink relay network scenario. A simple yet efficient technique to decompose the Robust Soliton Distribution (RSD) into two entirely different distributions by utilizing the concept of deconvolution is presented and these two different distributions are used at two different...
متن کاملUnequal error protection using LT codes and block duplication
Luby Transform (LT) codes are powerful packet erasure codes with low encoding and decoding complexity. We provide a simple method to improve the bit error rate performance of LT codes. Moreover, we exploit our method to design a new approach for unequal error protection with LT codes. We used simulations to compare our approach with a state of the art unequal error protection technique when the...
متن کاملUnequal Error Protection for Robust Video Transmission Using Multiplexed Codes
An error resilient video coding scheme based on unequal error protection over error prone channels is proposed. Due to the sensitivity of VLC to channel errors, a single bit error can cause loss of synchronization at the receiver, leading to catastrophic degradation of image quality. Multiplexed codes are an effective approach to combat losses of synchronization. In this paper, multiplexed code...

متن کاملUnequal Error Protection by Partial Superposition Transmission Using LDPC Codes
In this paper, we consider designing low-density parity-check (LDPC) coded modulation systems to achieve unequal error protection (UEP). We propose a new UEP approach by partial superposition transmission called UEP-by-PST. In the UEP-by-PST system, the information sequence is distinguished as two parts, the more important data (MID) and the less important data (LID), both of which are coded wi...
