Application of the m Sequence In the Bit Error Test of the Trunked Radio Receiver
XU Hai-chua · Microcomputer Information · 2009
In the performance test of the trunked radio receiver,the bit error ratio (BER) test is a necessary and important guide line,and finding the synchronized point is the key step in the BER calculation. Because the auto correlation coefficient of the m sequence has good two values characteristic,this paper uses it as the input signal source,and finds the synchronized point using the method that doing the sliding correlation operation between the input signal and the received signal. In PC machine the synchronized point is found and the BER is calculated by C and matlab software programming. The experiment shows that the method is simple and practical.
