MillimeterWaveProjectWinlab2021
v25 v26 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 ^([#hn Image 1])^26 * Began first tutorial on sending and viewing analog waveforms with Software Defined Radios (See picture) [[Image(analog.png)]] 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 [[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)]] 33 33 * Began researching OFDM (Orthogonal Frequency Division Multiplexing) 34 34 === Week 3 35 35 * Began sending digital waveforms with modulations (so they could actually carry information) using GNUradio and the benchmark_tx and benchmark_rx programs 36 * Tested out the differences between various modulations and sampling rates using the programs rx_ascii_art_dft to see the waveforms and benchmark_rx to note the quality of the transmission ^([#hn Image 3])^36 * Tested out the differences between various modulations and sampling rates using the programs rx_ascii_art_dft to see the waveforms and benchmark_rx to note the quality of the transmission (See picture) 37 37 * Found the limits of the b210 USRPs (the physical radios) at certain modulations in terms of the maximum sampling rate they could handle before underwriting (found the limits of the hardware). 38 38 *Began learning Bash to write my own scripts.
