[Discuss-gnuradio] packet loss at the tailing end

[Anjan Rayamajhi]

Hi,

I am trying to add convolution encoding and decoding to the benchmark scripts available in gnuradio and test using two N210s. A problem I have found is that the tailing packets for example last 10 packets out of a burst of 50 packets are not being received i.e. are not even passing the access_code_correlator block (decoding happens after the correlation successes with detection of start of the encoded packet) Could this be due to the high processing requirement for the decoding algorithm? 

When I remove the convolution codes, i..e use the provided benchmark scripts I don't find any such problems at all. What could be some of the possible reasons that a set of packets do not make it to the end of flow graph?
