- * viterbi_detector:
- * This part does the detection of received sequnece.
- * Employed algorithm is viterbi Maximum Likehood Sequence Estimation.
- * At this moment it gives hard decisions on the output, but
- * it was designed with soft decisions in mind.
- *
- * SYNTAX: void viterbi_detector(
- * const gr_complex * input,
- * unsigned int samples_num,
- * gr_complex * rhh,
- * unsigned int start_state,
- * const unsigned int * stop_states,
- * unsigned int stops_num,
- * float * output)
- *
- * INPUT: input: Complex received signal afted matched filtering.
- * samples_num: Number of samples in the input table.
- * rhh: The autocorrelation of the estimated channel
- * impulse response.
- * start_state: Number of the start point. In GSM each burst
- * starts with sequence of three bits (0,0,0) which
- * indicates start point of the algorithm.
- * stop_states: Table with numbers of possible stop states.
- * stops_num: Number of possible stop states
- *
- *
- * OUTPUT: output: Differentially decoded hard output of the algorithm:
- * -1 for logical "0" and 1 for logical "1"
- *
- * SUB_FUNC: none
- *
- * TEST(S): Tested with real world normal burst.
