Abstract :
Simultaneous broadcasting of multiple services in multiple-input and multiple-output (MIMO) broadcasting system is highly desirable. In this paper, the recently proposed technique, bit division multiplexing (BDM), is applied to MIMO broadcasting system, which significantly improves the spectral efficiency of multi-service broadcasting compared with conventional time division multiplexing (TDM) approach. Both average mutual information (AMI) analysis and bit error rate (BER) simulation results demonstrate that BDM can achieve higher overall transmission rate or lower minimum SNR requirement of multiple services. Furthermore BDM in MIMO system may decrease the complexity of MIMO detector accordingly.
