An explicit design of a linear dispersive space-time-frequency (STF) code is investigated with a design criterion achieving a high rate for frequency-selective channels when the partial interference cancelation (PIC) group decoding is implemented at receiver. With an appropriate grouping scheme, the proposed STF code is shown to obtain a similar diversity(More)
—Motivated by multi-step quantum teleportation of single-qubit states and two-qubit states with entanglement swapping, we present a small scale quantum network communication scheme based on entanglement of Bell states. In this scheme, it contains certain number of single-qubit quantum source nodes that teleport unknown quantum states to other nodes in the(More)
In our recent paper entitled"Quantum Quasi-Cyclic Low-Density Parity-Check codes"[ICIC 2009. LNCS 5754], it was claimed that some new quantum codes can be constructed via the CSS encoding/decoding approach with various lengths and rates. However, the further investigation shows that the proposed construction may steal some ideas from the paper(More)
