Hello all,
Lately, I am experimenting with an implementation of a point-to-point
On-off Keying communication system. I mostly prefer to use the USRP as
the receiver, in which I can capture samples and later process them
through Matlab. However, because of the algorithms I try to apply at the
receiver (packet/symbol synchronization, channel estimation,
carrier-frequency offset cancellation, detection) I have to deal with a
lot of delay at the receiver processing part. As a result, my
transmitter keeps sending packets which will either get lost or stored
at the fifo.
Therefore, I would like to know, if it is possible to construct a second
buffer (softwarely in Matlab) in order not to lose so many data packets.
Does anyone have an intuition about the way the fifo is used?
Thanks,
GS
