Computational expense

The rapid and ubiquitous introduction of the digital processing methods in radio communication systems led to the situation where the computational expense index gained a paramount importance. Qualitative indices of the system operation are directly related to this index.

The computational expense predetermines two main indices:

1) processing speed of computational modules;
2) quality of algorithms.

No doubt, a certain influence on the computational expense in communication systems has also the system of organizing the operation, external conditions and the professionalism of users. But these indices are of secondary importance because in the case of unfavorable basic parameters the computational expense will always be significant, and inevitably there will be significant limitations of the operation quality. The McWiLL system is designed as a fully digital one in terms of signal processing and organization of telecommunications. Digital algorithms for processing/control are used on all seven levels (with exception of the 1st level defined as ‘physical’) that form the model of the universal open system in accordance with the X.200 international standard. Moreover, according to the latest trends, digital methods are used for controlling the "physical level” equipment.  To this end, at the channel level, a branched MAC sublevel is used capable of supporting both the existing and future channel forming equipment. The latest scientific researches of Kailath School of the Stanford University form the basis of the digital processing. These rely on the super-fast computations using a priory information about the data mathematic structure. The McWiLL system itself is designed to support a wide range of specialized terminal equipment including subscriber radio stations, walkie-talkies, smartphones, digital communication modems, and M2M modems. The devices are built around chipsets developed by the company and their architecture was shaped with the focus on the specific tasks of radio communications.
