Any differential encoding or other data coding must be performed on the input vector before this modulation operation.

Be aware that the format of the incoming data must match the format the modulator block is expecting. GNURadio modulator blocks are inconsistent in their data type expectations. For instance, cpmmod_bc expects unpacked,signed bytes in (-1, 1), while gmsk_mod expects packed,unsigned bytes in (0, 1). In other words, the output ofgmsk_mod given the input vector [0xaa, 0x00] is equivalent to the output of cpmmod_bc given the input vector [1,255,1,255,1,255,1,255,255,255,255,255,255,255,255,255]
