In this paper, we contribute to the secrecy outage analysis of transmit antenna selection (TAS) with switch-and-examine combining (SEC) in the Multiple-input multiple-output (MIMO) wiretap channel. The complexity of SEC is lower than maximum-ratio combining (MRC) and selection combining (SC). The transmit antenna which maximizes the instantaneous signal-to-noise ratio (SNR) at the receiver is selected...
A user pairing method is proposed to improve the throughput and users' fairness performance in virtual multiple input multiple output (VMIMO) in 3rd Generation (3G) long-term evolution (LTE). This approach is based on post-processing signal to interference plus noise ratio (SINR) of each user, and takes both large scale and small scale fading into account, which renders more spatial multi-user diversity...
