Article Prunable collision free random interleaver design(Springer, 2012) Gazi, OrhanIn this article we introduce a new collision free prunable random interleaver. The suggested interleaver is a joint structure involving rectangular and S-random interleaver. It comprises a general model for all kind of collision free prunable random interleavers. In addition, it can be designed for any number of parallel processors and any length of information sequence vector and can be considered also as a template for collision free prunable interleavers. The proposed interleaver can be used with all kind of turbo-like codes. The performance of the proposed interleaver is measured with parallel decodable serially concatenated convolutional codes (PDSCCCs) and compared to the PDSCCCs' performance with collision full S-random interleaver.Conference Object Citation - WoS: 2Citation - Scopus: 3New Early Termination Methos for Turbo Decoders(Ieee, 2014) Gazi, OrhanTurbo codes have large latency due to iterative decoding steps and complex decoding algorithms To decrease the decoding delay it is essential to terminate the decoding operation as soon as there is sufficient information for data bits. Early termination can be achieved by defining stopping criteria beyond which negligible achievement is observed. In this article, we investigate some efficient stopping criteria based on the variance of extrinsic information and population of the bits below a predetermined threshold. We show that variance based method is better than its previously suggested counterparts, and threshold based method is the least complex one considering the available methods.
