Embodiment Construction
[0093] A specific uplink FDMA cellular system parameter configuration is given below to illustrate the implementation steps of the present invention. It should be noted that the parameters in the following example do not affect the generality of the present invention.
[0094] Uplink FDMA
Cellular system parameters
Set up
Cellular system model and layout
A regular hexagonal honeycomb grid, the simulation uses 7 small
Zone model, there are 3 sectors in each cell
User distribution
Random uniform distribution
The distance between cell base stations D
500m
The signal power varies with the distance between the user and the base station
L=128.1+37.6log 10 (R), the unit is dB,
R is the distance between the user and the base station, in Km
Shadow fading standard deviation
8dB
Shadow fading correlation distance
50m
Between cel...
