Bit error rates for a MIMO system in Rayleigh and Rician channels

Abstract

Multiple input multiple output (MIMO) systems, being under intensive research nowadays, are discussed under the aspect of bit error rates (BER) that can be achieved in indoor scenarios. This paper focuses on the influence of antenna diversity, a line of sight (LOS) signal and channel estimation errors onto the BER using BPSK and 16-QAM modulation. The developed simulation environment allows us to determine the necessary accuracy for channel estimation to achieve the desired BER performance in a MIMO channel under certain constraints like number of antennas, modulation scheme etc.
