I want to create a block which takes input of two streams ( Tx1 and Tx2 ) and give output of two streams,
o1 = a * Tx1 + b * Tx2
o2 = c * Tx1 + d * Tx2,
where a,b,c and d are complex constants.
Can anybody please help on how to realize this block in GNURadio. Any pointer towards what functions to use would be helpful. Also, should this be done at the python level or should a C++ block need to be written?
