In this paper, a simple design of a linear dispersive space-time-frequency (STF) code is proposed with a design criterion to achieve high rate for frequency-selective channels in terms of multipath when the Partial Interference Cancellation Group (PIC) group decoding is applied at receiver. With an appropriate grouping scheme as well as the PIC group decoding, the proposed STF code is shown to obtain...
An fast channel polarization is proposed to construct code sequences as an idea splitting input channels to increase the cutoff rate. The proposed code sequences related to the recursive construction of Reed-Muller code (RM) on the basis of the matrix G(2n), can achieve the symmetric capacity of arbitrary binary-input discrete memoryless channels under a low complexity successive cancellation decoding...
Polar code was proposed by Erdal Arikan as an incentive idea splitting input channels to increase its transition performance. The proposed code that is related to the recursive construction of Reed-Muller codes on the basis of 2-order square matrix G2, can achieve the symmetric capacity of arbitrary binary-input discrete memoryless channels. It has already been mentioned that in principle larger matrices...
We consider the iterative decoding of the Turbo-LDPC and Polar code. By using iterative decoding algorithm, we can get good performance and of new research programs. Turbo codes were introduced by Berrou. Polar codes were proposed by Arikan which can achieve the capacity of arbitrary symmetric binary-input channels. LDPC codes could be decoded in a similar manner to Turbo codes and polar codes, and...
In this paper, a new approach to construct LDMC codes is introduced. The new codes can be encoded efficiently at the transmitter side and support both of the inner-iterations and outer-iterations at the receiver side. Furthermore they can achieve the design rates and perform very well over MIMO channels.
A lot of knowledge has been accumulated and documented in the form of process models, standards, best practices, etc. The knowledge tells how a high quality software process should look like, in other words, which constrains should be fulfilled by a software process to assure high quality software products. Compliance checking for a predefined process against proper constrains is helpful to quality...
Since Adleman shows that DNA strands can be used to solve an instance of the NP-complete Hamiltonian path problem (HPP). DNA computing has been used to solve all kinds of difficult problems including neural networks. This paper put forward a DNA computing model of perceptron to implement linear categorizer function. The advantage of the DNA computing model is the great parallelism of algorithm which...
A quantum secure direct intercommunication scheme is proposed to exchange directly the communicators' secret messages by making use of swapping entanglement of Bell states. It has great capacity to distribute the secret messages since these messages have been imposed on high-dimensional Bell states via the local unitary operations with superdense coding. The security is ensured by the secure transmission...
Motivated by the elegant relationships of the row vectors of the Jacket matrix Jn and its inverse matrix Jn-1, which are both consisted of Fibonacci number sequence over the finite field GF(p), a novel network work code is constructed structurally with efficiency. The present network codes have advantages of eavesdropper-preventing and error-detecting ability, which are decided by the properly selected...
