—Based on incremental amplify-and-forward (IAF) relaying scheme, the exact closed-form outage probability (OP) expressions of the multiple-mobile-relay-based mobile-tomobile (M2M) cooperative networks with relay selection over N-Nakagami fading channels are derived in this paper. Then the OP performance under different conditions is evaluated through(More)
In this paper, we investigate the capacity of spatially correlated, multiple-input–multiple-output (MIMO) channels in a 60 GHz indoor environment. We first derive the correlation coefficients between two antenna elements as a function of the antenna spacing. Then, the standard deviation of the power azimuth spectrum (PAS) and the mean angle of arrival (AOA)(More)
The outage probability (OP) performance of multiple-relay incremental-selective decode-and-forward (ISDF) relaying mobile-to-mobile (M2M) sensor networks with transmit antenna selection (TAS) over N-Nakagami fading channels is investigated. Exact closed-form OP expressions for both optimal and suboptimal TAS schemes are derived. The power allocation problem(More)
