On the effective adaptive modulation polices for Non-orthogonal Multicarrier systems

In this paper new bit and power loading (BPL) algorithm is presented, which is suitable for application in non-orthogonal multicarrier (NOMC) systems. Its main idea bases on the J. Campello´s approach, originally designed for orthogonal multicarrier systems, like orthogonal frequency division multiplexing (OFDM). In the proposed solution, the NOMC-specific features are considered, i.e. two-dimensional processing and the presence of self-interference phenomenon on the transmitter side. The proposed modifications and improvements cause significant reduction of computation complexity, while ensuring high performance, and make the proposed algorithm well-suited for practical implementation. Such conclusions are confirmed by the presented simulation results.
