| Abstract(in English) | For P-MP system, carrier to co-channel and adjacent channel Interference ratio(C/Ico+ad)in normal circumstance may affect grade of service, cell cluster structure, and design of equipments. Owing to sharp reduction with azimuth at subscriber antenna gain, there is a big difference between C/Ico+ad in the normal case and that in the worst case. This paper developed caluculation method of C/Ico+ad in the normal case where subscriber station(SS)s exist uniformly and transmit randomly. As a result, following items were obtained. C/Ico+ad in the normal case is around 40dB or 50dB. That is 20 or 25dB bigger than C/Ico+ad in the worst case. Ico+ad in the normal case is attenuated in 3 dB because of SS's transmission power control. |
