Use of higher order modulations (HOMs) improves the spectral efficiency and hence allows to achieve higher throughput. This paper investigates factors that influence the performance of HOMs, such as 256-QAM and 1024-QAM, which are being considered for next-generation wireless technologies. In particular, impairments, such as phase noise, frequency offset, error vector magnitude (EVM) are investigated...
Coexistence of narrowband (NB) and multicarrier technologies will be a major concern in next generation wireless communication systems due to the co-channel interference (CCI) problem. In this paper, an efficient CCI cancellation method is proposed that may be utilized for an improved coexistence. The method treats both co-channel signals as desired signals and enhances them in an iterative manner...
