An improved Reed–Solomon (RS)-polar code concatenation scheme with a threshold is proposed. It applies successive cancellation list and hard-decision decoding based on the low-complexity chase algorithm. A new multiplicity assignment module is proposed to make it possible to realize the RS-polar code concatenation and facilitate hardware decoder design. The proposed scheme achieves high decoding performance,...
There are situations (e.g. for reverse engineering or formal verification) circuit designers would need to extract complicated arithmetic circuitry deeply embedded inside a fully synthesized (or manually touched) million-gate flattened netlist without the knowing of module boundary and IO positions. Besides not knowing the IO and boundary, a formal verification task like comparing two netlists implementing...
In this paper we propose a scheme to compare any two encoded optical signals by using differential detection and identify optical code sequence in the encoded data stream. Furthermore, we propose an algorithm to recover the original data from the derived optical code sequence. This scheme can be used to analyze the security performance of multi-optical-code based secure optical communication systems...
Cooperative communication has been shown that it is an effective way to achieve spatial diversity in order to combat the user-outage caused by effects fading channel. Except for amplify-and-forward (AF) and decode-and-forward (DF), compressed-and-forward (CF) is also an efficient forwarding strategy. In the existing CF protocol, the relay will switch to the DF mode when the source transmitted signal...
High data availability is an important feature of P2P storage system. Erasure coding is a common method employed to support the property. But the technique requires an original file to produce redundant data. On the contrary regenerating code, without maintaining the original file, solves the problem through collecting encoded information in a distributed way. However, there is a drawback in this...
