PERFORMANCE ANALYSIS
The typical performance measure for an RF link is the average
bit error rate (BER). The satellite subnetwork end-to-end
performance is related to the RF link performance by a
required average BER. The relationship between a channel
BER and the achieved carrier-tenoise density performance
depends upon the modulation technique and the channel
conditions. For the case of ideal linear modulation techniques
and an additive white Gaussian noise channel, this relationship
can be derived analytically. For the case of a random fading
channel this relationship can be derived through simulation, or
using a worst case assumption that all multipath energy is
equivalent to noise.
The digital RF communications link can be assured of
satisfactory average BER performance if the achieved carrierto-
noise power density ratio is greater than or equal to the
carrier-tc-noise power density raio required for communication
at the desired average BER:
