Summary The development of new hybrid diversity methods has been demanded by the continuous growth of information rates. These schemes achieve improved balance between hardware complexity and performance, in relation to conventional ones. In this paper, a new hybrid switched diversity system is proposed. It is called generalized multi‐branch switch and examine combining. The new scheme is a generalization of the classic one known as switch and examine combining with considerably improved performance. The performance of this scheme is analyzed over independent and identically distributed Nakagami‐ m fading channels using well‐known performance and complexity measures. More specifically, important performance metrics, such as the outage probability, the average bit error rate, and the capacity under different adaptive transmission policies, have been analytically studied. It is shown that the proposed approach offers an important improvement on the performance, without considerably affecting the complexity.
