Subject: [Discuss-gnuradio] a ridiculous observation when running thebenchmark_tx.py program!

 

Hi, all

         When I ran the benchmark program, I input the following two commands to transmit a data file.

         One is:

         ./benchmark_tx.py �Cf 170000000

         The other is:

         ./benchmark_tx.py �Cf 170000000 �CS 2

 

         In fact, by reading the program, I noticed the default value of samples_per_symbol is 2. So I think by using the argument �CS 2, there should be no impact on the program execution. But I found that the program runtime decreased from about 17s to 5s. Have anyone met this problem before and told me the reason for that? I am doing experiments on the performance analysis of the GNU Radio and can’t figure out the reason for that.

 

Thanks a lot
