Description: Femtocells are a promising solution for the provision
of high indoor coverage and capacity. Furthermore, OFDMAbased
femtocells have proven to be highly versatile when dealing
with cross-layer co-channel interference thanks to the allocation
of frequency subchannels. However, concerns still exist related
to the impact of the different access methods to femtocells in
an overlayed network. Femtocells based on a Closed Subscribers
Group, where only device owners are allowed connectivity introduce
severe interference to macrocell users. Platform: |

Description: The main RF interference sources in the Dual-mode Terminals and the required C/N for CDMA receiver operating normally are discussed first considering government regulatory requirements. Secondly, The C/N received at CDMA receiver input under the cases of Co-channel and adjacent channel interference generated by GSM transmission are calculated respectively. Finally, the solution for suppressing the interference of GSM transmission to CDMA is given and experiment results are shown. The result can be used for reference in the design of multimode RF products. Platform: |
