本程序设计了常用的几个坐标系的转换，从WGS—84与PZ－90坐标系的相互转换，以及空间直角坐标系与大地坐标系的转换。(This procedure has designed a number of commonly used coordinate system conversion from WGS-84 and PZ-90 coordinate system conversion, as well as the spatial Cartesian coordinate system and geodetic coordinate system conversion.)

16QAM软解调方式，适合与Turbo码、LDPC等结合，可按照次思路扩展到高阶调制和解调(16QAM soft demodulation method, suitable combination of Turbo codes, LDPC, in accordance with sub-ideas to be extended to higher order modulation and demodulation)

基于EM算法的混合COPULA（Frank、Gumbel和clayton）(EM algorithm based on hybrid COPULA (Frank, Gumbel and clayton))

利用BBO算法来优化网络负载均衡，达到很好的效果，比传统方法优越。很适合正在用智能算法优化网络映射的学者。(BBO algorithm to optimize the use of network load balancing, to achieve good results, superior to traditional methods. It is optimized for network mapping scholars intelligent algorithms.)

说明：  这个程序和我上传的上一个程序有关，它可以将上个程序收集到的频谱数据进行拼接，从而在全频段进行展示，还能计算频谱上的信号频谱带宽和频点 主要参数 start_freq %扫频中心频率fc的起始频率， stop_freq %扫频中心频率fc的截止频率 rtlsdr_fs %每一次扫频的采样频率，改变他会影响每次扫频的带宽 nfrmhold %每次扫频的帧数 nfft %fft点数 overlap %扫频频谱的重叠率(dataspecrumcatch, catch the spectrum and It can also calculate the signal spectrum bandwidth and frequency point on the spectrum)
