Wireless detonator chip

I need a microcontroller to check the CRC sum. I don't know how to implement such a scheme. The receiver should receive signals with a frequency of 200 Hz on a carrier of 90 MHz... This sequence must be recorded somewhere. Into some kind of memory. But I can't figure out when to start recording. If the recording start signal was false, then after the transmitter starts working, the receiver will incorrectly record the transmitted data. How do I start recording?

You send a preamble - look at Nigel's Manchester encoding routines.
