Abstract :
Qualitative and quantitative agreement between experimental and theoretical results for binary error probability for a coherent QPSK system degraded by intersymbol interference is given. The source of intersymbol interference is a delayed and attenuated replica of the transmitted signal which may represent several forms of observed multipath. Although the experimental results pertain to a particular 1 Gbit/s modem, the theory is applicable for any data rate.
