WebThis example shows the BER performance improvement for QPSK modulation when using log-likelihood ratio (LLR) instead of hard-decision demodulation in a convolutionally coded communication link. With LLR demodulation, one can use the Viterbi decoder either in the unquantized decoding mode or the soft-decision decoding mode. WebAug 15, 2014 · You can select the optional arguments from pg_proc, but you probably won't be able to parse their default values' expressions on PostgreSQL's side (because they can have different types).. select proargnames[pronargs-pronargdefaults+1:pronargs] optargnames, pg_get_expr(proargdefaults, 0) optargdefaults from pg_proc where … slow motion machining
