Blue

A 13 kHz mobile channel from the North Atlantic (MACE'10), recorded over a 3-7 km range with a moving transmitter and a 12-element vertical array.
  • Experiment:
    • Location: 40.2N, 70.5W
    • Date recorded: June 2010
    • Center frequency: fc = 13 kHz
    • Bandwidth: B = 5 kHz
    • Symbol rate: R = 107/2048 sym/s (approximately 4.9 ksym/s)
    • Distance: d = 3-7 km
    • Tx/Rx/water depth: dT/dR/dw = 30-60 m/50 m/100 m
    • Mobility: mobile (relative speed up to 1.5 m/s)
    • Receiving array: vertical, M = 12 elements, ℓ = 12 cm spacing (numbered top to bottom)
  • Parameters:
    • Sampling rate in delay: fs = 2R
    • Total delay coverage: up to 30 ms
    • Sampling rate in time: R/100 for the channel response, 2R for the phase/delay
    • Total time coverage: 1 minute
