| Abstract(in English) | We evaluate the phase difference distribution in multi-path propagation by computer, and find some parts theoretically. The distribution is discussed from two points of view in time and in frequency domains. 1) In the time domain, a) probability and cumulative density functions are derived, b) the distribution depends on the product of fading frequency ƒ_m and symbol interbal T_s, c) the dumulative value of beyond plus and minus π/4 in phase difference (p(|x|>π/4)) is calculated. 2) In the frequency domain, a) the distribution depends on the product of channel bandwidth ƒ_o and excess delay time τ_i, b) phase difference at a cumulative value of 50% is <2πƒ_oτ_i> and is zero off, c) the cumulative value of p(|x|<π/4) is also calculated. Furthermore, the distribution with thermal noise is simulated. As an example of application of the distribution, we estimate the BER of DQPSK by using the distribution, and this agrees well with the theoretical value. |
