The recommended code group format is lead code + synchronization code + data frame. The length of lead code should be as large as 10ms to avoid background noise, because the first bit of data received by RF receiver
RXB9 Module is prone to interference (i.e., zero-level interference), which will cause received data errors. So using CPU coding and decoding can add some garble before the data recognition bit to suppress the zero level interference. Synchronization codes are mainly used to distinguish them from leading codes and data. There are certain characteristics, so that the software can identify the synchronization code through a certain algorithm, and at the same time prepare for the receiving data of
RXB9 Receiver Module.
