I want to implement MIMO using gnuradio. I already could do differential and coherent(BPSK) communication link between two USRPs( daughter board Flex 2400 ). right now for channel estimation in MIMO I need to do reconfigure flow graph. As mentioned in www.gnuradio.org/trac/wiki/Tutori

Just tested the opengl implementation... Rocks hard ! Update times are really up on my C2D 2.4G E4600 / 2GB / Intel 82G33/G31 / Ubuntu Hardy. Had to do a "make clean" also, since it was reporting some top_block4dump error while running any GR code. Probably a lone case. In Ubuntu, you can get pyth
