The performance of mobile orthogonal frequency division multiplexing (OFDM) system is affected by the intercarrier interference (ICI). A recently proposed sequential probabilistic integer least squares (SPILS) algorithm remarkably improves the performance of ICI mitigation. The corresponding low complexity Quick SPILS (QSPILS) algorithm is also proposed to reduce the complexity of SPILS algorithm...
This paper introduces the Cloud-based Radio Access Network (C-RAN) architecture into heterogeneous network (HetNet), in which distributed antennas are connected to a cloud-based baseband processing unit through optical fibers. Among various opportunities realized by this architecture, our focus in this paper is on the spectral efficiency (SE) advantages achieved by cooperative transmission and its...
