Effect of space diversity technique in UHF band radio indoor propagation

In order to clarify the receiving condition in the whole room, in this paper, the received level contour map is created based on the measured data of the UHF band radio wave in the indoor environment. Moreover, this paper investigates the effects of applying the space diversity technique that have been well known to be effective techniques to improve the deep fading considering the space uncorrelation of the received level (M. Schwartz et al.) By use of the measured level data, in order to clarify the space diversity effects in the indoor environments, the correlation coefficients between two branches and the cumulative probabilities of the received level are evaluated in case that the space diversity techniques with selection combining are applied.
