Abstract

Software Radio is a kind of promising technology in today and future's communication systems. To share the resources of software radio systems to a large extent, we need to connect the instruments through backbone networks, such as the Multi-Service Transport Platform (MSTP), which is a dominating network technology that adopts both telecom and datacom traffic into existing transport infrastructures - Synchronous Digital Hierarchy (SDH). Virtual concatenation (VCAT) is one of the key technologies in MSTP. Compared with traditional contiguous concatenation, VCAT reduces transmission granularities, provides more flexibility to Network Management System (NMS) and as a result, improves the network efficiency greatly. In this paper, we introduce our design and implementation of VCAT module for a MSTP ASIC. The procedure of theoretical analysis to determine several important performance related parameters is also discussed in detail. The overall design has been thoroughly simulated and verified through our self-made FPGA board, and has been successfully applied in our MSTP ASICs. We believe our work is significant for future development of software radio technology.
