Abstract
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 through extensive computer simulations, in relation to the considered HOMs.
