Demod Method
Middle Demodulation response speed is fast. The advantage is that the
correct demodulation
can be made immediately after each
communication is started. The disadvantage is that if
there is a spike
mutation in the packet (a sudden abrupt increase in amplitude), it will
affect
the subsequent period of demodulation.
Average Demodulation response speed is slow. The disadvantage is that
it takes time for
each communication to demodulate correctly (usually
10-20 symbols). The advantage is that
the demodulation effect will not be
affected if there is a spike mutation in the packet (a
sudden abrupt
increase in amplitude).
The experience is that the spike mutation only exists in some special
applications, so it is
generally recommended that the demodulation
method of Middle can speed up the
demodulation and reduce the
receiving time.
Long-Zero Number
The user needs to input this value to tell the receiver how many
consecutive 0 there are at most in the packet. The receiver will modulate
the relevant parameters to ensure the best demodulation results.
CDR Type
In the packet mode, the user needs to detect Preamble or Sync. The
symbol rate clock recovery function has to be turned on, and the later
chapter will describe
how to use CDR in detail.
CDR Range
How to input Parameters when CDR = Tracing. The later chapter will
describe how to use CDR in detail.
