Abstract: The ability to use software defined radio (SDR) in the civilian mobile applications will open up the next generation of mobile devices to reality such as multi-standard personal wireless devices or ubiquitous wireless devices. Many challenges in commercialising SDR are still the subject of interest in the software radio research community. Four main issues that have been already addressed are performance, size, weight, and power. The investigation presents in-depth study of SDR inter-components communications in terms of total link delay related to the number of components and packet sizes in software communication architecture (SCA)-based systems. The study is based on the investigation of the controlled environment platform. Results indicate the total link delay did not linearly increase with the number of components and the packet sizes. The closed form expression of the delay was modelled using the logistic function in terms of the number of components and packet sizes. The model performed very well when the number of components was large.
