Scientific Challenges

Having a clear idea of relevant research areas in sdr is not easy because many parameters are not related to economical cost. For instance, military research has made its own development of sdr for its particular needs: US military sdr follows the sca communication architecture  [45] but this is usually not considered as a realistic choice for a commercial sdr handset. The targeted frequency band has a huge impact as sampling at high rates is very expensive, and trade-offs between flexibility, complexity, cost and power consumption have a big influence on the relative importance of the hot research topics.

Here are the relevant research domains where efforts are needed to help the deployment of sdr :
