/* * In the expected usage mode of our libgsmefr decoder as part of "soft TRAU" * uplink implementation, there will be times when the radio subsystem tells * us that a frame has been lost, but we don't have any errored bits to feed * to the decoder as ETSI canon calls for. We could of course call * EFR_decode_frame() with a dummy frame of all zeros and BFI=1, but the * EFR_decode_bfi_nodata() function provided in this module accomplishes * the same effect more efficiently. */ #include <string.h> #include "gsm_efr.h" void EFR_decode_bfi_nodata(struct EFR_decoder_state *st, int taf, int16_t *pcm_out) { int16_t params[EFR_NUM_PARAMS]; memset(params, 0, sizeof(int16_t) * EFR_NUM_PARAMS); EFR_decode_params(st, params, 1, 0, taf, pcm_out); }
