Abstract :
Nagata and Akaiwa (see ibid., vol.VT-36, p.100-13, 1987) have committed a principal error in evaluating the area mean power of the local mean power sums with log-normal distribution. This results in overly optimistic estimates of spectrum efficiency for various mobile radio systems. The correct expression for the area mean power is given. An alternative technique for the determination of the area mean power and variance of the joint interference is also reviewed. This is more appropriate for the shadowing phenomena occurring in mobile communications than the (corrected) method proposed by Nagata and Akaiwa.<>
