Abstract

The interference of TD-SCDMA with 1.4MHz carrier bandwidth coexisted with adjacent 1.4MHz and 1.6MHz carrier bandwidth is analyzed.Firstly

ACLR and ACS value are calculated in theory for base station and user equipment with 1.4MHz and 1.6MHz carrier bandwidth respectively.Secondly descent of ACLR and ACS are analyzed and compared with BS and UE equipment test result.Finally system capacity loss is calculated when adjacent carrier are coexisted for 1.4MHz and 1.6MHz carrier bandwidth respectively by system level simulation.The results of simulation are very valuable for 1.4MHz frequency plan of TD-SCDMA.
