System consideration on LTE and LTE-Advanced requirements for receiver channel filter

In this paper, the mobile receiver channel filter requirements as extracted from the 3GPP (3rd Generation Partnership Project) Release 10 Specifications for LTE-Advanced are investigated. A brief discussion will explain the choice of Direct Conversion receiver architecture in mapping the specifications in this study. The focus of this study is on Adjacent Channel Selectivity (ACS) and In-band Blocking requirements. The specification tables were translated into graphical diagrams that visualize the spectrum around the required channel frequency at Zero-IF. This illustrates channel filter frequency response which allows for easier design procedures.
