Hi,you are right. The current implementation does not use soft-bits but feeds hard bits into the decoder.
In 2013, I used the soft-input Viterbi decoder from the IT++ library. http://itpp.sourceforge.net/4.3.1/convcode.html Best, Bastian On 01/17/2018 11:36 AM, sumit kumar wrote:
Hi, I am doing some proof of concept using gr-ieee 802.11. The paper by author [1] says that it uses softbits, however in the method*constellation::decision_maker(const gr_complex *sample)*, I see outputs as hardbits. Am I missing something here i.e. any particular commit or branch where the softbits implementation is there.Its very important for my algorithm to use softbits :-/ [1] https://conferences.sigcomm.org/sigcomm/2013/papers/srif/p9.pdf Sumit
