Very clean. > Both corr_est_cc and modulate_vector were written and contributed to GNU Radio by Nick Foster and Andy Walls, and are intended as a more general replacement for corr_and_sync, and were recently merged into master for eventual release in 3.7.8. Tom Rondeau, Sean Nowlan, and I are working on better packet/burst mode processing and the above is a nice addition to that. The modulate_vector function/block may undergo some changes as we're trying to figure out the best way to deal with group delay in the pulse shaping filter. -- Johnathan Corgan Corgan Labs - SDR Training and Development Services http://corganlabs.com
