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.
