In this study, the authors propose a diversity‐combining scheme with transmit antenna selection (TAS) and output‐threshold generalised selection combining (OT‐GSC) receiver. It is shown that the proposed TAS/OT‐GSC can achieve similar performance as compared to the TAS/GSC with a reduced number of channel estimates when the predetermined signal‐to‐noise ratio (SNR) threshold is optimised. The outage probability, average output SNR, and symbol‐error rate (SER) expressions of the proposed TAS/OT‐GSC scheme are derived and presented over independent and non‐identically distributed Rayleigh‐fading channels. The analytical expressions are validated by simulation results. The trade‐off comparisons in terms of the SER and number of channel estimates between the TAS/OT‐GSC and TAS/GSC are discussed. Lastly, the capacity between the TAS/OT‐GSC and TAS/GSC is compared.
