A heterogeneous hardware architecture with the programmable vector processor EVP as key component can support WLAN UMTS and other standards. A detailed rationale for the EVP architecture based on the analysis of a number of key algorithms as well as implementation and benchmarking results are described. Keywords and phrases vector processing software-defined radio 3G baseband processing wireless LAN rake receiver. 1. INTRODUCTION Future mobile handsets will need to support multiple wireless communication links potentially including 2G cellular 3G cellular wireless local area network WLAN personalarea network PAN broadcast and positioning. A layered structure of such a future network adapted from 1 is shown in Figure 1 and Table 1. These layers are to be integrated in a common flexible and seamless IP core network supporting global roaming and a single access number per user. This requires both horizontal intrasystem and vertical .
