Automated Receiver Design and Optimization for 4G Wireless Communication Systems

Abstract

This paper presents the design methodology and underlying algorithms of a tool developed for automated receiver design and optimization for fourth generation (4G) wireless communication systems. An algorithm to systematically design and optimize the receiver budget for the multi-standard case is introduced. The goal of this algorithm is to find a multi-standard receiver budget that meets or exceeds the specs of the addressed wireless standards while keeping the requirements of each of the receiver blocks as relaxed as possible. This tool offers RF engineers a deep insight into the receiver behavior at a very early stage of the design flow. It models the impact of some circuit non-idealities using a high level of abstraction. This reduces the number of design iterations and, thus, the time-to-market of the solution. The reuse of already available intellectual property (IP) blocks is also considered in the tool. This can result in a significant cost, reduction of the receiver implementation
