Hi Marcus:
Thank you for your reply.Sorry for my unclear introduction to
my question.I apology for this.
I just want to know whether someone encounter the similar
question of mine.My question is this:I have two usrps.One is transmitter while
the other is receiver.
1.I use the transmitter to send signals to the receiver.
2.And then receiver calculate the message (very shot).And
through the tcpip,the receiver transmit the message to the transmitter.
3.The transmitter resend again.
Because the receiver keep receiving during this processing.So
in the interval of the transmitter sending,the receiver receive some noise.I
don't want receive the noise.
Have some ideas about this?Experts.Thank you.
Best regards,
zs

Hello xd,
You're expecting us to guess what you know:
What are we seeing in that diagram? What are the axes and how are they scaled?
Also: some information of message length, the amount of data you need to pass
through network, why latency is a problem etc would always help.
Generally, GNU Radio can't do magic. If your data processing/forwarding
introduces latencies, there's nothing you can do.
"TCP/IP transmission" doesn't necessarily give you any indication on how fast
something happens -- generally, ack'ing protocols like TCP might be a bad
choice in limiting latency.
Best regards,
Marcus

Hi all:
Thank you in advance.
Environment: gnuradio 3.7.5
The picture below shows the received signal.I will try my best to
explain my problem.I use one usrp N210 to send signal and the other usrp
receive the signal and then transmit the message by the tcpip to the
transmitter.Then the transmitter re-send signal again.I think the way of tcpip
transmission is so fast.But it has the latency as the below picture shows.Have
some ideas to solve it?And have some tools in grc to solve it?Thanks so
much.(the signal inside the blue circle while the latency is interval of
signal).
Best regards,
