Loss of packets during reception

hi,
In the problem i am working on, the receiver sends a particular
frequency
to the transmitter via the ethernet to which both receiver and
transmitter
get tuned. the transmitter should then transmit the specified number of
bytes at that frequency. then the receiver sends the next frequency and
the
process repeats. the problem i’m facing is that all the packets
transmitted
are not received at the receiver. timeouts occur at the beginning and
end
and sometimes in the middle of the frequency range. why does this
happen?
can anyone explain what is meant by transmitter saturating the receiver
front end?
Kindly help,
anma

theres some threads about this, u should take a look

from what i gather, the loss of packets occurring at the end of
transmission
is due to the transmitting USRP shutting off too early, theres a delay
from
sending it and it actually being in the air and then receiving it, and
because it shut off before it actually waited for the last few packets
to
get airborne, the receiver never gets the ending ones. to rememdy this
you
should have ur transmitting USRP to send data in a different modulation
at
the beginning and end of a transmission, that way the receiver will only
pick up the data in the correct modulation and the transmitter will not
shut
off too early.
