In communications systems,a communication channel may change with time. Coherence time is the time duration over which the channel impulse response is considered to be not varying. Such channel variation is much more significant in wireless communications systems, due to Doppler effects.

Property Value
dbo:abstract
  • En els sistemes de comunicacions, el canal pot canviar al llarg del temps. El temps de coherència és el lapse de temps durant el qual la resposta impulsional del canal es considera constant. Aquesta variació en el canal és especialment significativa en els sistemes de comunicacions sense fil, a causa de l'efecte Doppler. (ca)
