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…

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…
