Hybrid multiple input multiple output (MIMO) beamforming can be divided into shared and split MIMO beamforming architectures, according to different concatenations of radio frequency (RF) chains and antennas. This paper considers split MIMO beamforming for millimeter wave system, i.e., each antenna subarray is only connected with one RF chain. To obtain analog precoding matrix and combining matrix,...
Spatial Modulation (SM) is utilized to overcome the negative influences of inter-channel interference (ICI) and enhance the spectral efficiency in multiple-input and multiple-output (MIMO) systems. Bit-interleaved Coded Spatial Modulation (BICSM) is proposed with the aim of improving the Bit Error Rate (BER) performance of SM systems. In our paper, a novel approach based on adaptive dual-interleaving...
In this paper, an enhanced power-save multi-poll (PSMP) combining conventional PSMP with Downlink Multiuser Multiple Input Multiple Output (MU-MIMO) is proposed to further improve the energy efficiency of wireless local area network (WLAN) communication system, especially for multiuser WLAN system. The energy consumption in PSMP downlink transmission time (DTT) of the conventional PSMP and the proposed...
In this paper, we utilize a new study method that is under independent case of multiple optical orthogonal codes to derive the probability function of MOOCS-OPS networks, discuss the performance characteristics for a variety of parameters, and compare some characteristics of the system employed by single optical orthogonal code or multiple optical orthogonal codes sequences-based optical labels. The...
We show firstly multiple hops system of multiple OOC sequences-based optical labels for optical packets switching (MOOCS-OPS), we then consider the performance of MOOCS-OPS, for the first time. Some results of MOOCS-OPS are obtained and analyzed to verify accepted tolerance of multiple hops performance of MOOCS-OPS.
