Switching rate and receiver performance of binary modulations with the selection‐and‐stay combining over independent and correlated Nakagami‐m fading channels

Abstract

SUMMARYThe dual-branch selection-and-stay combining (SSTC) is analyzed for diversity reception on independent and correlated Nakagami-m fading channels, where the conventional selection combining (SC) is employed only at the switching instance, and the receiver uses the selected branch till its signal-to-noise ratio (SNR) estimation is lower than a preset threshold. In this combining scheme, the receiver only needs to continuously estimate the SNR of the single selected branch. For the performance analysis of SSTC, the switching rate and the average bit error rates (BERs) of different binary coherent and non-coherent modulations are evaluated. Numerical results based on the analysis and simulations are illustrated. According to the analysis and numerical results, the SSTC outperforms the existing switch-and-stay combining in the senses of the average BER and switching rate.

Enhanced switch combining for spatial diversity with a switch window over correlated Nakagami‐m fading channels

“…Moreover, a dual‐observation rate (DOR) is defined as a measurement of simultaneous dual‐branch observations. We will show that ESC can achieve performance matched to SSTC/SECps, while has a much smaller DOR than SSTC/SECps , which implies that ESC consumes less power than SSTC/ SECps.…”

“…Notice that, not like the SEC or SECps, the performance of SSC using more than two diversity branches remains the same as that of dual‐branch SSC. In and , as an alternative of SECps, the dual‐branch select‐and‐stay combining (SSTC) scheme was proposed and analyzed for binary signaling over correlated Nakagami‐ m fading channels. Basically, SSTC and SECps will have the same receiver performance.…”
