Converts cartesian coordinates in WGS84_XYZ to geodetic coordinates in WGS84_LLA. Vectorized version.

The function impulsive_noise generates non-gaussian noise with inputs of beta, gamma,and the power of noise is 1 in W or 0 in dB. The noise can be defined either real or complex. The other functions generate QAM symbol and insert a vector to another vetor with specific locations

低压电力线载波通信的OFDM系统仿真，采用了压缩感知的方法进行信道估计，分别选取不同导频数目与LS算法比较，仿真效果良好。(OFDM power line carrier communication system simulation, using the compressed sensing method for channel estimation, respectively, to select a different number of pilot and LS algorithm, the simulation results is good.)

Abstract The key of developing high frequency wideband communication system is how to model the HF wideband channel. Some HF wideband models are discussed and compared in this paper, including Vogler model, parallel subband model, two improved Watterson models and Pseudo- Deterministic model. As a deterministic model, Volger model basically describes the characteristics of HF wideband channel, but it also needs to be improved. The improvement of Vogler model is given in this paper.
