Abstract :
The equivalent transmission-path model, which was proposed by the authors, has a function to assess the bit error rate (BER) due to intersymbol interference (ISI) in a Nakagami-Rice fading environment with a simple formula. In this paper, improvement of usability is pursued taking the similarity of BER map shape in the delay difference between two waves into account. Moreover, an extended method predicting overall BER and frame error rate (FER) affected by both thermal noise and ISI is proposed, and accuracy is evaluated by computer simulation. Finally, a self-consistent flowchart showing how to calculate overall BER and FER in Nakagami-Rice fading environments is presented
