| 摘 要： | 随着各类二进制偏移副载波(Binary Offset Carrier,BOC)调制信号的广泛应用,特别是AltBOC,TD-AltBOC及ACEBOC等,其复杂的发射方式,使得传统的信号功率标定方法不能用于标定其单支路信号功率。提出了一种功率分配功率标定方法,该方法在高功率条件下标定信号总功率,在正常功率条件下分配各支路信号功率。给出了该方法的原理、步骤,分析了其使用要求。实例测试表明,该方法可实现BOC调制信号单支路功率标定,且误差优于0.5 dB。

| Abstract: | With the wide application of BOC modulated signal,especially AltBOC,TD-AltBOC and ACEBOC etc.,the conventional signal power calibration method cannot be used to calibrate the single channel signal power due to the complex transmitting mode.A power calibration method through power allocation is proposed,which performs signal total power calibration under high power condition,and performs power allocation of each channel signal under normal power condition.The principle and procedure of this method are given,and its application requirement is analyzed.The practical test results show that this method can calibrate the power of single channel of BOC signal with an error below 0. 5 dB. |
