Sample File

Throughout this documentation we will be using a sample file that contains the I/Q samples of a 802.11a packet at 24 Mbps (16-QAM). It'll be helpful to use a interactive iPython session and exercise various steps discussed in the document.

Download the sample file from here </files/samples.dat>, the data can be loaded as follows:

import scipy

wave = scipy.fromfile('samples.dat', dtype=scipy.int16)
samples = [complex(i, q) for i, q in zip(wave[::2], wave[1::2])]
