Coded polarization multiplexing as a MIMO scheme for the LMS channel

In this paper, we propose polarization multiplexing as an ideal candidate for next-generation GNSS systems like GPS and Galileo. After describing in detail a new model of MIMO LMS channel, we show simulation results for the proposed scheme concatenated with a state-of-the-art Turbo code. A slow and a fast scenario are considered and both show that PM offers a better performance than other schemes from the literature. Also, we show the performance comparison of different receiver options for PM, by both considering iterative and noniterative receivers, with both optimal and suboptimal demapping.
