Are you looking to have these put into the core or do you wish to work on it some more first? These are very useful and I look the finite state machine formulation. Bob Achilleas Anastasopoulos wrote: I just realized I had the wrong website. The correct one is: www.eecs.umich.edu/~anast

[Discuss-gnuradio] Problem in gnuradio-core build

2006-04-12 Thread Robert W. McGwier
Something was recently changed in the gnuradio-core make that causes an error: Notice the waiting for jobs. This was compiled with make, not buildit. I was having a problem with doing the build on darwin, MacOSX and then I ran into the same problem at Frank Brickle's. By the way, the build

[Discuss-gnuradio] Generic finite state machine / Viterbi algorithm implementation

2006-04-12 Thread Achilleas Anastasopoulos
Hi everybody, I finally found some time and ported in gnuradio-2.7 my old ANSI-C implementation of a generic framework for finite state machines (FSM) and corresponding sequence detection using the Viterbi algorithm (VA). The code is more generic (and I guess slower; 117 Kbps for an 1/2 CC with 1

[Discuss-gnuradio] Questions on Tx path

2006-04-12 Thread jjw
I have been reading about how the Tx path works in the USRP and was slightly confused. I know that some of the interpolation is done in the FPGA and some of it is done in the DUCs on the external chips. Noting the following code from class usrp_standard_tx: /*! * \brief Set output mux con
