The Effective Throughput of MISO Systems Over κ-μ Fading Channels

Abstract

The effective throughput of multiple-input–single-output (MISO) systems communicating over both independent and identically distributed (i.i.d.) and independent and nonidentically distributed (i.n.i.d.) κ-μ fading channels is investigated under delay constraints. New analytical expressions are derived for the exact effective throughput of both channels. Moreover, we present tractable closed-form effective throughput expressions in the asymptotically high- and low-signal-to-noise-ratio (SNR) regimes for i.i.d. κ-μ fading channels. These results enable us to investigate the impact of system parameters on the effective throughput of MISO κ-μ fading channels. We demonstrate that as the affordable delay tends to infinity, the effective throughput is increased to the classic ergodic capacity. By contrast, the effective throughput of delay-constrained near-real-time systems fails to approach the ergodic capacity.
