New combining schemes for partial decisions using one‐bit and two‐bit information of the received samples are derived for Rayleigh fading channels. Compared with previous partial decision combining schemes, these new schemes have either better performances or simpler structures, or both. Simulation results show that some of the new schemes can achieve considerable performance gains over the conventional partial decision combiner in Rayleigh fading or log‐normal shadowed Rayleigh fading, whereas their structures are much simpler than the conventional partial decision combiner. This confirms the advantages of the newly designed combining schemes. Copyright © 2011 John Wiley & Sons, Ltd.
