Stable-matching-based subcarrier assignment method for multimode PON using a multicarrier variant of subcarrier multiplexing

In this paper, an adaptive subcarrier assignment method based on a stable matching algorithm is considered. From the performance comparison with other assignment methods (Hungarian-algorithm-based, contiguous and interleaved), our assignment method, while of relatively low complexity, resulted in a satisfactory performance in terms of per-ONU and overall achievable throughputs, and also it responded to the traffic demands.
