For the communication system of mobile cellular, as the interference alignment, which had been proposed in the original IA scheme is based on precoding, that combined with decoding can fully eliminate the interference between the effective channels. Its new application is on precoding and suboptimal power allocation for the downlink multi-cell multi-user wireless system, with each BS performs equal...
The authors propose a generalised multi-layer architecture for the phase shifter network (PSN) in hybrid analogue/digital beamforming (BF), which provides flexible trade-offs between the performance and implementation complexity. By changing the layer number, the authors can adjust the complexity of the PSN and the achievable performance. A two-stage BF algorithm is adopted, in which the analogue...
High data rate space time/frequency block coding (STBC/SFBC) suffers from interference due to its non-orthogonal structure of the effective channel. This paper presents new STBC/SFBC scheme to suppress interference with an aid of angle feedback. The proposed scheme achieves the full diversity gain with the spatial code rate of two by rotating constellation symbols in STBC/SFBC codewords. We find the...
