In this paper, we compared several software defined radio platforms and proposed the general architecture of GPP (General Purpose Processor)-based soft base stations. Then, we studied on the scheme design of resource allocation and algorithm optimization in soft base station implementation. Finally, as an instance of our study above, a prototype of GPP-based soft base station referring to 3GPP LTE was realized and evaluated. With its evaluated performance, GPP's capability on processing high speed wireless signal flow was verified, which showed us a promising prospect for GPP-based soft base stations in the next generation wireless systems.
