Summary :

This paper develops an efficient multi-user bit and power allocation algorithm in an iterative fashion for discrete multi-tone systems. The model of the interference channel is considered, where the transmit signal from each user causes interference to the other users. The scheme aims to minimize the total transmit power while satisfying the required data rate of each user. The proposed algorithm is shown to greatly reduce the computational complexity of the existing algorithm with negligible amount of transmit power increment as demonstrated in the simulation results. The proposed methodology can be applied to the DMT-based system, but is also feasible for either wired or wireless communication systems with the model of the interference channel and another type of modulation scheme.
