There exist online resources such as [1], [2]. None of RFNOC blocks available on E312 can do that. You will have to write a new RFNOC block in Verilog/VHDL, then synthesise an FPGA image (expecting there is enough space), push it into the E312, and then instantiate the block using C++ API or GNU Radio.
