Universal filtered multicarrier (UFMC) is a promising new waveform that eliminates cyclic prefix and performs filtering on a chunk of successive subcarriers. Therefore, it is suitable for applications with requirements on high spectral efficiency and low latency. However, the limited bandwidth may be an obstacle for reliable communication in frequency selective channels. This paper proposes a new...
This paper proposes an Interference Alignment (IA) scheme in two-user downlink frequency selective broadcasting channels, referred to as semi-blind interference alignment (semi-BIA). Based on the frequency selectivity structure, interference can be aligned at users without precise channel coefficients at the Base Station (BS) nor reconfigurable antennas at users. Compared with traditional interference...
