Feedback Limited

Feedback Limited offers a whole suite of specialized solutions for multi-user MIMO CSI feedback. Our algorithms (with multiple US patents pending) include:

• vector quantization of channel state information
• mitigation of the feedback channel delay and errors
• MIMO channel prediction
• vector quantization aware channel estimation
• other relevant technologies: feedback codecs, indexers, schedulers etc.

Our algorithms are designed with the actual system implementation in mind, and hence are capable of much better performance than abstract theoretical approaches. All our solutions are highly asymmetric, which means that system design is very computationally intensive, however, the actual operational algorithms are very simple to implement in the base station and receiver DSPs.
