中文说明：代码的主要目的是要找到发射器和接收器之间的范围。我是在生成具有 16 频率的信号跳 BPSK 调制这种信号是变送器。虽然接收器接收信号与添加到它一些噪音。找到两者之间的距离我们用四个技术称为交叉相关法，最早高峰搜索法、 最小方差法和相移法这些四种技术，它生成的发射器和接收器之间的距离。
English Description：
The main objective of the code is to find the range between transmitter and the receiver.In i generated a signal with a 16 frequency hopped with BPSK modulation this signal is transmitter. while the receiver receives the signal with some noise added to it. To find the distance between the two we use four techiques called cross correlation method, earliest peak search method, minimum variance method and the phase shift method these four techniques it generates the distance between the transmitter and the receiver..
