Abstract

In this paper, we present a downlink multiuser Multiple-Input Multiple-Output (MIMO) joint detection scheme with secure physical layer. Within a data block, an arbitrary user´s Quadrature Amplitude Modulation (QAM) modulated signal is protected by the pseudo-randomly defined scrambling codes, in order to prevent the other users from eavesdropping the whole Forward Error Correction (FEC) block. We can adjust the density of scrambling codes in the data block, to balance the trade-off between the improved physical layer security and the slight loss of sum rate. Finally, we analyze the Bit Error Ratio (BER) performance and provide the corresponding union bound. We also present the achievable rate of the proposed scheme by Monte Carlo simulation.
