一种考虑互耦计算大型阵列天线辐射和散射场的新方法(A large array antenna mutual coupling calculation of radiation and scattering field to consider new methods)

论述了风力发电并网的PLL技术，基于传统PI-PLL技术基础上，以双同步旋转坐标系建立电网电压不平衡的数学模型。(mbalance of power grid voltage phase lock loop)

1.升余弦窗首尾8点数据值:12bit-> 1-1RAM_OUT_CNT_RN10 formal 采用移位相加的方式来取代相乘运算，节省资源。 (1 liter inclusive 8:00 cosine window data values​ ​ : 12bit-> 1-1RAM_OUT_CNT_RN10 formal using shift and add a way to replace multiplication, save resources.)

OFDM 系統加AWGN的性能模擬,訊號的Mapper使用QPSK,Guard interval 取資料的符元是1/4，輸出信號與原始信號比較出錯誤率。(Plus AWGN performance of OFDM system simulation, signal Mapper use of QPSK, Guard interval operators access to information, the yuan is 1/4, the output signal and compare the original signal error rate.)

Modern wireless device have sleep mode which greatly reduce the duty cycle of the power supply.Consider the effect of different duty cycles and transmit times to see the wide range of battery lifetimes one may expect before recharging. results is being plotted of battery lifetime as a function of the duty cycles & duration of the wake up mode.
