摘要（英）：

The invention discloses a method and a device for processing signals based on a broadcast mode automatic dependent surveillance. The method comprises the following steps of obtaining pulse amplitude information, consisting of message amplitude information, by sampling spreading discontinuous oscillation signals; obtaining pulse information and a leading head mark according to the pulse amplitude information; obtaining a reference amplitude value according to the leading head mark, the pulse information and the pulse amplitude information; obtaining a confidence level bit and a data qualification bit of a data bit in the message amplitude information by combining with the leading head mark, the pulse information and the pulse amplitude information according to the reference amplitude value; and correcting message information in the spreading discontinuous oscillation signals according to the obtained confidence level bit and data qualification bit of the data bit in the message amplitude information. The embodiment of the invention can efficiently reduce error data bits in the message information and improve the stability of message signals.
