Patent ID: 8306496

Claim:
A millimeter-wave data transmission characteristic analysis apparatus for use with a radio communication system which takes into consideration a propagation channel characteristic when a reception apparatus receives a radio signal of a millimeter wave band, transmitted from a transmission antenna of a transmission apparatus, via a reception antenna, said apparatus comprising: a computing device that computes h(t) expressed by the following equation (1) as a channel response to the propagation channel characteristic: h ( t )=βδ( t ) (1) where β is a complex amplitude expressed by the following equation (2), and δ(t) is a Dirac's delta function, β = 1 P loss ⁢ ( μ D D ) ⁢  G t ⁢ ⁢ 1 ⁢ G r ⁢ ⁢ 1 + G t ⁢ ⁢ 2 ⁢ G r ⁢ ⁢ 2 ⁢ Γ 0 ⁢ exp ⁡ [ j ⁢ 2 ⁢ π λ f ⁢ 2 ⁢ h 1 ⁢ h 2 D ]  ( 2 ) where G ti : gain of the transmission antenna in the transmission apparatus (i=1; direct wave, i=2; reflected wave); G ri : gain of the reception antenna in the reception apparatus (i=1; a direct wave, i=2; reflected wave); D: distance between a transmission antenna and a reception antenna at a time of generating of a channel response; μ D : average value of D; h 1 : height of the transmission antenna; h 2 : height of the reception antenna; P loss : path loss in free space; Γ 0 : complex reflection coefficient; λ f : wavelength of the radio signal; and said computing device respectively handling D, h 1 , and h 2 as mutually independent random variables according to a uniform distribution or a normal distribution, and parameters, such as a distribution range, a center value, an average, and dispersion, are determined based on a usage mode of a target radio communication system.
