Multilevel coding(MLC)is a commonly used polar coded modulation scheme,but challenging to implement in engineering due to its high complexity and long decoding delay for high-order modulations.To address these limitat...
In this work,we study the performance of one shot and concatenated deleting machines(DMs).We show that the output state of one shot DMs are mixed inseparable,and do not violate Bell's inequality but can be used as a t...

Dear editor,Polar codes,along with a low complexity successive cancellation(SC)decoding,were discovered in[1]by Ar?kan.It is shown in[2]that the bit errors with the SC decoding are correlated.To improve the performanc...
Even though much advancements have been achieved with regards to the recognition of handwritten characters,researchers still face difficulties with the handwritten character recognition problem,especially with the adv...
A novel serially concatenated GMSK system is proposed for satellite communications subject to low SNR,limited power and spectrum resources.First,we design a Nonrecursive continuous-phase encoder(NRCPE)based GMSK based...
