Abstract :
An information-theoretic analysis of two interference models, one introduced in the work of D. Chase and L.H. Ozarow (IEEE Trans. Commun., vol.COM-27, p.441-8, Feb. 1979) and the other, the conventional model, is given. The computational cutoff rate is computed for the two channel models for BFSK (binary-frequency-shift keying) on conventional receivers using L diversity and square-law combining for soft decision, and majority logic decision for hard decision on each diversity branch. There are two motivations for the work. The first is to observe the relative importance of the assumptions of hard and soft decisions and L diversity for the two models. The second is to use this information-theoretic approach to determine how sensitive the results are to the model. Numerical results are presented
