Josh Blum 40890e46ab Remove mmap dependencies with QFile

QFile implements cross platform file mapping and removes this dependency entirely.
Also simplifies the file size and error to string handling logic.

inspectrum

inspectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.

Try it

Prerequisites

cmake
fftw 3.x
liquid-dsp >= v1.3.0
pkg-config
qt5

Build instructions

Build instructions can be found here: https://github.com/miek/inspectrum/wiki/Build

Run

./inspectrum [filename]

Input

inspectrum supports the following file types:

*.cf32, *.cfile - Complex 32-bit floating point samples (GNURadio, osmocom_fft)
*.cs16 - Complex 16-bit signed integer samples (BladeRF)
*.cs8 - Complex 8-bit signed integer samples (HackRF)
*.cu8 - Complex 8-bit unsigned integer samples (RTL-SDR)

If an unknown file extension is loaded, inspectrum will default to *.cf32.

Features

Large (100GB+) file support
Spectrogram with zoom/pan
Plots of amplitude, frequency, phase and IQ samples
Cursors for measuring period, symbol rate and extracting symbols
Export of selected time period, filtered samples and demodulated data
