摘要：
In this letter, the joint optimization problem of power allocation and subcarrier-relay assignment in orthogonal-frequency-division multiplexing-based decode-and-forward relaying network is addressed. The objective is to allocate the resources fairly to maximize the signal-to-noise ratio of the poorest channel. We propose a simple optimal algorithm with polynomial time complexity to solve this nonconvex optimization problem.
