GPS_SPP
GPS伪距单点定位，包括导航文件、观测文件、精密钟差和精密星历的读取，对流层Hopfield模型，电离层K8模型，采用最小二乘法，最后通过调用matlab来计算测站坐标。对GPS编程初学者是很好的编程哦。(GPS pseudorange point positioning, including navigation documents, observation files, precision clock bias and precision ephemeris read, Hopfield model troposphere, ionosphere K8 model, using least square method, and finally by calling matlab to calculate station coordinates. The GPS program is a good program for beginners oh.)

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.

Digital image face detection had been developing so much in this last decade. The searching for the best
method is still walking until today. This face detection research is using color model based segmentation method
combined with template matching. There are 4 main process in this research. First, motion detection is used to
minimize the size of the image by subtracting image n with image n+m. Then, by using YCbCr color model based
segmentation, the image is separated by skin color area and non-skin color area. Third, is to reduce the noise by
using the blurring way and by filtering its wide. The last one is matching the area that last with template that has
been prepared to detect which area is face. The result of the research, from 217 images and 10 videos , shows
that this method reach up to 70,5 face detection accuration procentage.
