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
