Abstract
In this contribution we study the impact of transmitter and receiver impairments on the throughput for MIMO and 64 QAM transmissions in an evolved HSDPA system. A simple additive white Gaussian noise model is used to model impairments in the transmitter and receiver chain. The investigation is performed through computer simulations both on link and system level. It is found that the impact from transmitter and receiver distortions is rather small for MIMO with 16 QAM while the impact when 64 QAM is used is more pronounced.
