Comments on A New Parity Check Stopping Criterion for Turbo Decoding
Yuejun Wei, Yuhang Yang, Lili Wei +1
A parity-check stopping (PCS) criterion for turbo decoding is proposed in [1], which shows its priority compared with the stopping criteria of Sign Change Ratio (SCR), Sign Differe…
Joint Shortening and Puncturing Optimization for Structured LDPC Codes
Yuejun Wei, Yuhang Yang, Ming Jiang +2
The demand for flexible broadband wireless services makes the pruning technique, including both shortening and puncturing, an indispensable component of error correcting codes. The…
Increasing Security Degree of Freedom in Multi-user and Multi-eve Systems
Kun Xie, Wen Chen, Lili Wei
Secure communication in the Multi-user and Multi-eavesdropper (MUME) scenario is considered in this paper. It has be shown that secrecy can be improved when the transmitter simulta…
Design of Convergence-Optimized Non-binary LDPC Codes over Binary Erasure Channel
Yang Yu, Wen Chen, Lili Wei
In this letter, we present a hybrid iterative decoder for non-binary low density parity check (LDPC) codes over binary erasure channel (BEC), based on which the recursion of the er…
Optimal Upward Scaling of Minimum-TSC Binary Signature Sets
Lili Wei, Wen Chen
We consider upward scaling an overloaded min-TSC binary signature set and propose an optimal solution based on improved sphere decoding algorithm. Instead of previous suboptimal ap…
Integer-Forcing Linear Receiver Design with Slowest Descent Method
Lili Wei, Wen Chen
Compute-and-forward (CPF) strategy is one category of network coding in which a relay will compute and forward a linear combination of source messages according to the observed cha…
