Joint Source-Channel Estimation Using Accumulated LDPC Syndrome

Source correlation estimation is an important issue remained in Slepian-Wolf Coding (SWC), while a counterpart issue in noisy transmission is channel noise estimation. This letter considers the transmission of SWC bitstream over a noisy channel. We show that it is possible to estimate both source co...

Popis
Shrnutí:Source correlation estimation is an important issue remained in Slepian-Wolf Coding (SWC), while a counterpart issue in noisy transmission is channel noise estimation. This letter considers the transmission of SWC bitstream over a noisy channel. We show that it is possible to estimate both source correlation and channel noise using an accumulated Low-Density Parity-Check (LDPC) syndrome.
