The Block Shift Network (BSN) is a new topology for interconnection networks in multiprocessor systems. BSN is a class of networks defined by several parameters, and has a constant number of links/node for some given parameters. Many popular networks such as the hypercube, the shuffle-exchange, and the complete networks, are instances of the BSN for different parameters. Performance of BSN has ...

a direct-sequence signal with binary phase-shift keying (BPSK) or differential block diagram of direct-sequence systemn with BPSK or DPSK: a transmitter. Differential Phase Shift Keying. ▫ For a standard telephone circuit with S/N of 3000 (30. dB) and A block diagram of a QPSK modulator is shown in the next. differential phase shift keying (DPSK) modulations is that both Block diagram of the ge...

In this brief, a generalized topology of block shift networks (BSNs), named generalized block shift network (GBSN), is proposed for interconnection networks in clusters. The BSNs possess many desirable topological features, such as flexibility in node degree, small diameter and average distance, and easy VLSI implementation. However, the regular structure of each block in the BSN is not suitabl...

Recently Ott, Tomforde and Willis introduced a notion of one-sided shifts over infinite alphabets and proposed a definition for sliding block codes between such shift spaces. In this work we propose a more general definition for sliding block codes between Ott-Tomforde-Willis shift spaces and then we prove Curtis-Hedlund-Lyndon type theorems for them, finding sufficient and necessary conditions...

A convolutional code has memory over a short block length. This memory results in encoded output symbols that depend not only on the present input, but also on past inputs. An (n,k,m) convolutional code is implemented using k-input, n-output linear sequential system with a shift-register having m stages. In practice k and n are small and m is large to achieve low error probabilities. In the par...

Counter mode is well described in [8], which summarizes its advantages and reviews its security properties. Essentially, counter mode defines an additive stream cipher, given a block cipher with a fixed key, in which the keystream is the concatenation of the output blocks of the cipher with the input blocks defined by the integers in ascending order. We call this encryption mechanism integer co...
