摘要:
A method for determining whether a baud rate of a frequency modulated (FM) signal received by a receiver matches a predetermined baud rate. A parameter other than the baud rate is detected and used to confirm whether baud rate detection should be made, or whether if made, is reliable. The parameter is frequency deviation of the received FM signal, or other suitable parameters of the received FM signal.
