Collision Communications is developing advanced multi-user detection, MIMO, parameter estimation and scheduling technology to enable significant capacity gains in todays wireless communication systems.
Communications systems have traditionally relied on multiple access protocols that avoided interference. Although suboptimal in terms of maximizing spectral efficiency, interference avoidance allows for the development of simple receivers. With the advent of more powerful processors and the development of practical techniques to exploit the interference it is now possible to develop receivers that decode multiple simultaneous data streams overlapping in time and frequency. This results in substantial capacity gains without the need for more spectrum or cell splitting.
The receivers leverage the extensive IP portfolio of Collision Communications centered around Multi-User Detection (MUD) technology. MUD based receivers, in contrast to single user receivers, attempt to model multiple data streams rather than treating the interference as noise. The MUD based receiver decodes multiple data streams by exploiting dimensionality between the signals. These receivers are being practically realized in the form of advanced single user MIMO, multiuser MIMO and interference cancelers.
Collision Communications primary focus is developing advanced multi-user detection, MIMO, parameter estimation and scheduling technology for LTE.
