摘要: A description is given of a relatively simple derivation the bit-error probability for lightwave communications system using an amplitude-shift-keying (ASK) pulse modulation format and employing optical amplifiers such that amplified spontaneous emission noise dominates all other sources. Mathematically, this represented as Fourier series expansion with coefficients are assumed to be independent Gaussian random variables. The in closed analytical form derived by approximate evaluation several integrals appearing analysis. author uses theory derive approximation finds it overestimates rate one two orders magnitude. >
