[Discuss-gnuradio] A little help with using a block in benchmark_tx..plz

[Mir Ali]

Hi friends,

I want to modify benchmark_tx.py so that I can send data over usrp such that I spread the data before transmitting. Since I took a wrong approach in working on this I have a little difficulty. I wrote a gnuradio C++ block that spreads each bit of data into a gold code sequence. The input to this block is a stream of bits and output is a stream of bits  that represent a gold code sequence of length N. My problem is how will I use this block in either benchmark_tx or transmit_path. I looked at these two codes and understood most of it but can't figure out where and how should I insert this block. A little help would be appreciated. 

Thanks
Ali
