This contains data PacketInfo_Vel#.m for the emulation with velocities of 0, 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275 km/h, file new_plotter.m for plotting time differences between packets received and for comparing frequence against db, and a file load_data.m which loads all files and plots all files.
ACE Emulator, Vehicle A - 10,000 Packets
Download Vehicle A m-file: Vehicle_A.zip (50 MB)
This contains data PacketInfo_Vel#.m for the emulation with velocities of 0, 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275 km/h, file new_plotter.m for plotting time differences between packets received and for comparing frequence against db, and a file load_data.m which loads all files and plots all files.
When loading a PacketInfo_Vel#.m file, the variables are:
NodeIDs <2x10000>
-1st row is the partner ID
-2nd row is the Antenna ID.
-10,000 is the total number of packets
PacketData <7x10000>
-1st row is time stamp in seconds
-2nd row is time stamp in microseconds
-3rd is goodPackets
-4th is otherBadPackets
-5th is partnerBadPackets
-6th is rxBytes
-7th is txBytes
Sec <1x10000>
-1st row is time stamp in seconds
USec <1x10000>
-1st row is time stamp in microseconds
chanBB <1x10000>
-1st row is chanEstsStruct agc_BB
chanRF <1x10000>
-1st row is chanEstsStruct agc_RF
chanEstsI <64x10000>
-Rows represent chanEstsStruct I component
chanEstsQ <64x10000>
-Rows represent chanEstsStruct Q component
pkStatus <1x10000>
-1st row is the Packet Status
