Orientation adaptive transmit polarization diversity for branch power equalization
Huang, Yu Chieh & Senadji, Bouchra (2009) Orientation adaptive transmit polarization diversity for branch power equalization. In The 5th International Wireless Communications and Mobile Computing Conference, 21-24 June 2009, Leipzig, Germany.
Branch power equalization and increased system robustness against antenna orientation in transmit polarization diversity systems is achieved through precoded transmission of elliptical polarization. Elliptical polarization offers two main benefits over traditional polarization diversity systems. Firstly, it is able to facilitate power coupling between orthogonal polarizations and reduce the system sensitivity to antenna orientation. Secondly, when the operation parameters for elliptical polarization are chosen carefully based on channel information, branch power equalization is achieved for arbitrary transmitter orientation. In this paper, we articulate the parameters which need to be pre-coded at the transmitter to achieve power balance. The closed form solutions for optimal cross polarization discrimination are presented, assuming the full knowledge of channel statistics.
