On the antenna efficiency of coexisting networks with broadcast and point-to-point channels (Invited Paper)

We investigate the coexisting network of hybrid broadcast and point-to-point channels, where there is a public message required by each receiver except its own private message in the broadcast channel. Based on distributed zero-forcing approach, the minimum antenna configuration is deduced, under the condition of least antennas at each receiver. Then we propose a linear transceiver design for the network. Performance analyses including the antenna efficiency and achievable rate are provided and further validated by simulations.
