  Abstract

This paper implements the 3GPP standard WCDMA physical layer voice channel by using Universal Software Radio Peripheral (USRP) board, a software radio general purpose hardware provided by NI, and Visual System Simulator (VSS), a software that guarantees real-time interoperability with USRP. While most other implementation papers are focused on the physical layer, this paper implements a part of the MAC layer and sets it according to the bandwidth characteristics and packet structure defined in the 3GPP standard for system performance verification. The performance of the system was confirmed by using the spectrum analyzer through bandwidth of transmission signal, EVM of reception state, and code domain power (CDP).
