Low Complexity Coefficient Selection Algorithms for Compute-and-Forward

open access: yesIEEE Access, 2017
Compute-and-forward (C&F) has been proposed as an efficient strategy to reduce the backhaul load for distributed antenna systems. Finding the optimal coefficients in C&F has commonly been treated as a shortest vector problem, which is NP-hard ...

Estimating the Number of Wideband Radio Sources [PDF]

open access: yesJournal of Electrical and Computer Engineering Innovations, 2016
In this paper, a new approach for estimating the number of wideband sources is proposed which is based on RSS or ISM algorithms. Numerical results show that the MDL-based and EIT-based proposed algorithm havea much better detection performance than that ...
