Multiple input multiple output techniques combined
with orthogonal frequency division multiplexing (MIMO-OFDM)
provide a promising approach for wireless systems. However, a
serious drawback of the OFDM system is the high peak-toaverage
power ratio (PAPR), which may severely affect the
power efficiency of RF power amplifiers. In this paper, we
propose a simple method to reduce the PAPR of MIMO-OFDM
signals based on the use of unused subcarriers. Instead of
processing the signals at each transmitter separately, a peak
cancelling signal is generated at one antenna and is then applied
to all the others with only simple modifications. Simulation has
shown that a minimum 2 dB reduction in PAPR can be achieved
for all transmit signals using this approach. As the signal
processing is nearly all done at a single transmitter, repetition of
the operations at each transmitter is avoided, and therefore the
overall cost of the system can be significantly reduced.

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.)
