The universal filtered multicarrier (UFMC) is an appealing technique to eliminate out-of-band emission (OOBE) for\nfifth-generation (5G) networks. However, its signals that are modulated to the carriers, which are on the edges of one\nsubband, are influenced by the filter. In this paper, an interference cancelation scheme is proposed to suppress the\ninterference and to improve the multiuser system performance. Here, interference cancelation subcarriers are inserted\non the edges to reduce the filter interference. This scheme ensures that the operating subregion or subband supports\nthe variable bandwidth allocation to meet the requirements of 5G networks. Simulation results show that the bit error\nrate (BER) performance improves by 4 and 7 dB compared with that of the conventional UFMC when the\ncorresponding Eb/N0 is 15 and 20 dB. Comparisons with both the standard OFDM and the GB OFDM are also\nreported. The results demonstrate that the proposed UFMC scheme outperforms the other two systems, especially\ncompared with the GB OFDM system under the condition of the same spectral efficiency.
