Abstract

In this paper new Bit and Power Loading (BPL) algorithm is presented, which is suitable for application in Non-orthogonal Multicarier (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.
