A 2x2 multiple-input multiple-output (MIMO) architecture using dual-polarized antennas (DPAs) is considered with orthogonal frequency division multiplexing (OFDM). The performance of DPAs is evaluated for adaptive polarization (AP) transmission techniques in time-varying multipath channels impaired by polarization mode dispersion (PMD) and polarization-dependent loss (PDL). AP transmission techniques considered include power gain maximization, polarization dispersion minimization for interference avoidance, polarization multiplexing with waterfilling, and a suboptimal multiplexing strategy that enables direct recovery of the polarization multiplexed streams, thereby simplifying the design of the receiver. Measured time-varying dual-polarized channel realizations from mobile-to-mobile experiments are used to estimate the capacity, diversity, and interference avoidance performance of the adaptive approaches.

S60官方视屏播放器程序，可以装到手机上运行，但是在模拟器上运行会出问题。据说是因为视屏播放服务器的内核有问题，不能在模拟器上用。本人手机上测试成功。(S60 official video player program can be installed to run on mobile phones, but will run in the simulator problems. It is said that is because the screen play of the core server has problems, should not use the simulator. I test the success of mobile phones.)
