Channel (communications) - Channel Performance Measures

Channel Performance Measures

These are examples of commonly used channel capacity and performance measures:

  • Spectral bandwidth in Hertz
  • Symbol rate in baud, pulses/s or symbols/s
  • Digital bandwidth bit/s measures: gross bit rate (signalling rate), net bit rate (information rate), channel capacity, and maximum throughput
  • Channel utilization
  • Link spectral efficiency
  • Signal-to-noise ratio measures: signal-to-interference ratio, Eb/No, carrier-to-interference ratio in decibel
  • Bit-error rate (BER), packet-error rate (PER)
  • Latency in seconds: propagation time, transmission time
  • Delay jitter

Famous quotes containing the words channel, performance and/or measures:

    How old the world is! I walk between two eternities.... What is my fleeting existence in comparison with that decaying rock, that valley digging its channel ever deeper, that forest that is tottering and those great masses above my head about to fall? I see the marble of tombs crumbling into dust; and yet I don’t want to die!
    Denis Diderot (1713–1784)

    Just as the performance of the vilest and most wicked deeds requires spirit and talent, so even the greatest demand a certain insensitivity which under other circumstances we would call stupidity.
    —G.C. (Georg Christoph)

    I was surprised by Joe’s asking me how far it was to the Moosehorn. He was pretty well acquainted with this stream, but he had noticed that I was curious about distances, and had several maps. He and Indians generally, with whom I have talked, are not able to describe dimensions or distances in our measures with any accuracy. He could tell, perhaps, at what time we should arrive, but not how far it was.
    Henry David Thoreau (1817–1862)
