Latency Profiling for Sca Software Radio

Timing and latency are critical design parameters in the development of a communication system. With software radio and packet based methods emerging as viable replacements for traditional static solutions, different approaches are necessary to analyze the timing characteristics of these communication environments. This paper presents important concepts for performing timing and latency profiling within the OSSIE SCA software radio framework operating on the Linux operating system. Furthermore, relevant factors and parameters pertaining to latency performance are measured and compared. Specifically, the operations of inter-component communication within a collocated environment are explored.
