Architecture of a software radio system based on cluster of workstations

Conventional software radio architectures cannot perform signal processing using application level software or have limited capability. To solve these problems, this paper proposes a new architecture that can perform signal processing using application level software on cluster of workstations. This paper introduces key technologies from RF to baseband. Especially, detail designs are given for core technologies of PCI card and parallel processing. Based on these principles, wireless voice communications for four standards are realized on the system. Theory and practice prove that this is a scalable, more ideal software radio and is a promising one with potential.
