I didn't know of WSR08.
Seems like a very nice conference about Software Radio.
There are three GnuRadio presentations:
Session 6: GNU Radio
14:00 h GNU Radio Based Cognitive Signal Identification and Classification
Platform
W. M. Brown (Metric Systems Corporation, California, USA), J. E. Clark
III
14:25 h Implementation of OFDM Power Allocation Strategy in GNU Radio Framework
M. Zivkovic (RWTH Aachen University, Germany), C. Liu, R. Mathar
14:50 h Soft-DVB: A Fully-Software Gnuradio-based ETSI DVB-T Modulator
V. Pelegrini (University of Pisa, Italy), G. Bacci, M. Luise
Too bad I heard about it this late, otherwise I would have applied for doing a
GnuRadio presentation too.
(It looks like the submission has been closed since nov 30 2007)
I found info about the conference at:
