2006-08-15 Thread Tom Rondeau
That's probably mostly due to a versioning problem. The reference phase argument is no longer used. What the Costas loop is expecting, instead, is (alpha, beta, max_freq, min_freq, order). The order is the order of the Costas loop. Use 2 for BPSK and 4 for QPSK. This determines how the slicer behav

Hello, I am working on demodulating a BPSK signal (a manchester coded stream of pseudorandom bits.) I'd like to use a gr_costas_loop_cc block to recover the carrier. However, when I try to create the block with all five args (alpha, beta, max_freq, min_freq, and ref_phase) as floats, python r

Hi Michael, Having thought about this a little more, I don't think this problem is limited to the osx-audio. I have tried this also on my osx: 1) convert a complex dat file to a num file for gnuplot 2) plot the num file in gnuplot On os x I get zeros for all the converted points from the dat file,
