Hi Karan, If you installed this gr-cdma module with DENABLE_DOXYGEN=ON, you can find the html documentation in usr/local/share/doc/gr-cdma/html/index.html This html gives a general description of the module and contains the documentation of all the c++ blocks used (flag_gen, chopper, vector_insert2), and all hier blocks. For the python blocks (kronecker_filter, freq_timing_estimator), you open your python and do: *import cdma,* *help(cdma) #for a general look of cdma* *help(cdma.kronecker_filter) #for checking the documentation of the block kronecker_filter. * Please feel free to reply if you have any additional questions or suggestions.
