GPS数据收集测试工具,异步传输。用于手机GPS定位器上传的数据。该工具仅为测试工具.(GPS data collection and testing tools. Used for mobile phone GPS locator upload data. The tool is only for testing tools (agreement for the valley rice GT02 series))

说明：  基于MATLAB的OFDM信道估计算法，使用了PN序列作为导频，两种导频处信道估计处理方法，中间特别加入了相位估计处理(MATLAB-based channel estimation algorithm for OFDM using PN sequence as a pilot and two pilot channel estimation Department treatment methods, particularly the middle to join the treatment phase estimation)

该算法是迄今为止我找到的最好的最完整的单载波频域均衡的原理。众所周知，时域均衡一直是接收机的瓶颈能估，频域均衡则要简单的多。频域均衡使用基于块传输的机制，类似于OFDM，并且是单载波的。接收机十分完整，包含载波同步、帧同步等，最重要的均衡处理。(This algorithm is the best and the most complete single carrier frequency domain equalization principle I have found so far. As we all know, time domain equalization is always the bottleneck of the receiver, and frequency domain equalization is much simpler. Frequency domain equalization is based on block transmission mechanism, which is similar to OFDM and is single carrier. The receiver is very complete, including carrier synchronization, frame synchronization, and so on, the most important equalization processing.)

说明：  GPS伪距动态单点定位的计算公式,分析单点定位误差与几何强度因子GDOP之间的关系,并研究了当观测卫星数仅为必要的4颗时定位精度的降低情况,画出了GDOP与平面定位精度之间的等值线关系图,并研究了GDOP与定位精度之间的相关性。(the kinematic positioning formula using GPS pesudorange is given. The relationshipbetween error of single point positioning and geometry dilution of positioning(GDOP) is analysed. The worse situation in which only 4 pesudoranges are used in positioning is introduced. The relation contour between plane error of positioning and GDOP is given. Also studied is the correlation between positioning accuracy and GDOP. )
