find_lts()

def find_lts.find_lts	(		iq,
			thresh = 0.8,
			us = 1,
			cp = 32,
			flip = False,
			lts_seq = []
	)

    Find the indices of LTSs in the input "iq" signal (upsampled by a factor of "up").
    "thresh" sets sensitivity.

    Inputs:
        iq: IQ samples
        thresh: threshold to detect peak
        us: upsampling factor, needed for generate_training_seq() function
        cp: cyclic prefix
        flip: Flag to specify order or LTS sequence.
        lts_seq: if transmitted lts sequence is provided, use it, otherwise generate it

    Returns:
        best_pk: highest LTS peak,
        lts_pks: the list of all detected LTSs, and
        lts_corr: the correlated signal, multiplied by itself delayed by 1/2 an LTS
