To isolate the decoder performance, you may want to use the same encoder while varying the decoder implementation. For instance:
To isolate the decoder performance, you may want to use the same encoder while varying the decoder implementation. Also, you may want to investigate the performance with a particular MODCOD. The following examples are based on QPSK3/5 with normal FECFRAME:

- `bench/fec/bench_bch --enc 0 --dec 0 --nframes 10000`
- `bench/fec/bench_bch --enc 0 --dec 1 --nframes 10000`
- `bench/fec/bench_bch --enc 0 --dec 2 --nframes 10000`
- `bench/fec/bench_bch --enc 2 --dec 0 --nframes 1000 --fe 1000 --n 38880 --k 38688 --t 12`
- `bench/fec/bench_bch --enc 2 --dec 1 --nframes 1000 --fe 1000 --n 38880 --k 38688 --t 12`
- `bench/fec/bench_bch --enc 2 --dec 2 --nframes 1000 --fe 1000 --n 38880 --k 38688 --t 12`

> Note: Make sure to compile gr-dvbs2rx in Release mode so that the best performance is achieved, as instructed [previously](#dependencies).
The following results were obtained with the above commands using `--enc 0` and varying the decoders on an Apple M2 Max CPU:
