Iterative turbo decoder analysis based on density evolution
We track the density of extrinsic information in iterative turbo decoders by actual density evolution, and also approximate it by consistent Gaussian density functions. The approximate model is verified by experimental measurements. We view the evolution of these density functions through an iterative decoder as a nonlinear dynamical system with feedback. Iterative decoding of turbo codes and o...

متن کاملPerformance Analysis Based on Density Evolution on Fault Erasure Belief Propagation Decoder
In this paper, we will present an analysis on the fault erasure BP decoders based on the density evolution. In the fault BP decoder, messages exchanged in a BP process are stochastically corrupted due to unreliable logic gates and flip-flops; i.e., we assume circuit components with transient faults. We derived a set of the density evolution equations for the fault erasure BP processes. Our dens...

— In order to have reliable communication, channel coding is often employed. Turbo code as a powerful coding technique has been widely studied and used in communication systems. Turbo coding is an advanced forward error correction algorithm. A standard component in third generation (3G) wireless communication systems. Third generation (3G) mobile communication systems aim to provide a variety o...
