In this paper, we propose a fast MPI algorithm for Monte Carlo approximation PageRank vector of all the nodes in a graph, named Fast Fibonacci Series-Based Personal PageRank. In the latter paper we will call it FFSB algorithm for short. The basic ideal is very efficiently computing single random walks of a given length starting at each node in a graph. More precisely, we design FFSB, which given a...
In this paper, a low-complexity power-efficient iterative detection scheme for differentially encoded MPSK transmission over AWGN and Rayleigh fading channels is presented. As the main contribution, a novel APP coherent demodulator, which well suits for iterative processing, is derived under the optimal bit-based MAP criterion. The implementation of iteration is not trellis-based, and needn’t reconstruct...
