You probably want to take a look at the usrp2_version branch to see how to get the transmit code working with the hier_block2 API, and then modify it to work with the USRP1. Two things: you cannot transmit the 802.11b waveform through the USRP1 (you don't have enough bandwidth - in the original code base I believe they simply skipped the DSSS step, and transmitted the pulse-shaped DPSK-modulated signal), also I believe the usrp2_version branch transmit code fixed some of the bugs in the original transmit code (i.e. using a USRP2, the transmit code could send a standard-compliant waveform).
