A new simple, yet effective two-step bit-and-power-loading algorithm is described for multicarrier transmission. The coarse bit and power allocation to the subcarriers is done at the first step by the means of the direct mapping of the transmit power or bits with regard to the channel gains. Three ways of the final power and bit assignment are proposed at the second step. The algorithm reaches the...
In this paper, a novel pragmatic bit and power allocation algorithm for Non Orthogonal Frequency Division Multiplexing (NOFDM) systems is presented. It is based on the well-known Campello approach and takes into account the lack of orthogonality between adjacent waveforms. Simulation results in a typical NOFDM wireless applicative scenario show the effectiveness of the proposed algorithms.
