(this is directly from a verilog design in simulation! this didn't get converted to analog nor modulated onto a carrier or anything of the sort)

oh this is just a simulated verilog design, that constellation isn't from any sort of analog signal

i do have an fpga dev board that could run this but i don't have an oscilloscope :(

Y no amplitude noize?
-
it's data from a verilog design so it's all digital and without any sort of noise ;;

Explains the quantisation too I guess.

Looks nice! Did you try different filters?
-
heh that's actually a bit difficult to change because the response of the gaussian filter (with the right time constant, 0.3) is baked with a sinusoid to create lookup tables so it's not trivial to swap out intersymbol filtering ;;

oh well. just get right to impersonating my gsm base station fam

Decent enough that I guessed it wasn't from a physical system :P

may i ask what you are building? i follow gsm somewhat but this is kind of above my pay grade.
