v27 v28 24 24 * Learned how to use some initial Linux commands and access nodes (i.e. remote computers) in Orbit Lab 25 25 * Discovered how to image nodes to load a previous software setup 26 * Began first tutorial on sending and viewing analog waveforms with Software Defined Radios (See picture) [[Image(analog.png,width= 500px)]]26 * Began first tutorial on sending and viewing analog waveforms with Software Defined Radios (See picture) [[Image(analog.png,width=1000px)]] 27 27 === Week 2 28 28 * Sent analog waves of various shapes (Square, Sinusoidal, and Sawtooth), gains, sampling rates, wave frequencies, and center frequencies … … 30 30 * Learned what WinSCP is and how to use it to get files from Orbit Lab nodes onto a personal laptop 31 31 * Figured out how to use WinSCP to transfer supplied code to a node 32 * Studied and adapted MATLAB code to plot waveforms in the time and frequency domains (see frequency plot below) [[Image(image1.png )]]32 * Studied and adapted MATLAB code to plot waveforms in the time and frequency domains (see frequency plot below) [[Image(image1.png,wodth=1000px)]] 33 33 * Began researching OFDM (Orthogonal Frequency Division Multiplexing) 34 34 === Week 3 … … 74 74 * Finished scripting/automating the data collection process (including the naming of files to include metadata about the sampling rate and other factors at which the signal was sent) 75 75 * Found a better way to account for noise by taking a sample of measurements with no signal transmission, finding the midpoint of each resulting graph, and averaging those midpoints to find the general noise level (as opposed to just assuming the edges of each graph necessarily represented the noise level). 76 * Took 20 samples of each sampling rate to find a more accurate plot comparing sampling rate vs excess area with a 90% margin of confidence bar [[Image(Image9.png )]]76 * Took 20 samples of each sampling rate to find a more accurate plot comparing sampling rate vs excess area with a 90% margin of confidence bar [[Image(Image9.png,width=600px)]] 77 77 78 78 === Week 10
