pilot_finder()

def plot_hdf5.pilot_finder	(		samples,
			pilot_type,
			flip = False,
			pilot_seq = [],
			seq_length = 64,
			cp = 0
	)

Find pilots from clients to each of the base station antennas

Input:
    samples    - Raw samples from pilots and data.
                 Dimensions: vector [1 x num samples]
    pilot_type - Type of TX pilot (e.g., 802.11 LTS)
    flip       - Needed for finding LTS function

Output:
    pilot     - Received pilot (from multiple clients)
    tx_pilot  - Transmitted pilot (same pilot sent by all clients)
