Effect of Transmitter and Receiver Impairments on the Performance of MIMO in HSDPA (pdf)

Abstract:
In this contribution we study the impact of transmitter and receiver impairments on the throughput for MIMO and 64QAM 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 16QAM while the impact when 64QAM is used is more pronounced.
