AMPS cell transmitter interference to CDMA mobile receiver
Khalid Hamied, G.P. Labedz · 2002
There exists significant interference from an AMPS base transmitter to a CDMA mobile receiver. This interference is severe when the CDMA mobile gets close to a same-system noncolocated AMPS site or close to other-system AMPS site. We investigate the interference of AMPS cell site to a CDMA mobile subscriber unit in 1:3 colocated AMPS and CDMA deployment (or other pattern). A quantitative evaluation of the interference was carried out including the side-band noise and an exact evaluation of third order intermodulation. The paper covers same system interference as well as other system interference.
