Due to the widespread usage of wireless devices, how to securely transmit the data on physical layer has been paid much attention. Recently, a physical layer security algorithm called directional modulation came up, which can avoid the information leakage in any direction except the desired direction. On the basis of Directional Modulation, we propose a Physical Layer Security scheme by using dual base station. What's more, we employ the Multiple Directional Direction Modulation on two base stations to transmit data stream modulated by the improved QAM program. Compared to the traditional Directional Modulation Scheme, this scheme ensure the data stream can only be properly demodulated in the specific location where the legitimate user is, instead of all the area in a certain direction. In addition, we propose a simulation model to show the bit-error-rate (BER) of the received signal in the coverage area of the two BS. From the simulation result, it is obvious that our scheme can effectively narrow the range of the low BER area, which means can be correctly demodulated, to a specific area.
