In this paper, we present a novel integer programming (IP) optimization formulation for downlink OFDM subchannel allocations in a multicell system and propose viable sub-optimal so...
Abstract— This paper proposes the opportunistic power allocation (OPA) scheme for random beamforming with a limited feedback rate. Without the channel state information, the prop...
— Trellis codes based on linear congruential recursions have recently been introduced as powerful source codes. For a modest computational complexity they offer excellent rate di...
In this paper, we study the security of an image scrambling algorithm based on Space-Filling Curves (SFC). A random SFC is a pixel permutation that changes the scanning order with...
— Different coherence dimensions can be considered to improve the performances of an algorithm for computing collision translations of pairs of convex polyhedra. The algorithm’...
